The whistle goes and Portugal will take a slender advantage to Sweden next Tuesday. Ronaldo wins his duel with Ibrahimovic, but Zlatan will no doubt look to respond in the second leg. Thanks for following the game with me. Stay here for report, reaction and more from Lisbon.
Three minutes of added time to play as Portugal seek to extend their advantage. Ronaldo has the ball in the net but only after Pereira cuts it back after a goal-kick had been awarded.
Elmander does leave the field, but it is at the instruction of his coach rather than the referee. Alexander Gerndt replaces the Norwich forward.
Ronaldo hits the bar! Almeida's great cross from the left finds his captain at the far post but Ronaldo crashes his header against the frame of the goal.
Prior to the goal, Elmander was lucky to escape a second yellow card after he went down very easily under a challenge from Pereira. Portugal wanted a red card after the apparent dive but the Sweden forward stays on.
Veloso's inviting cross from the left is met by a diving header from Ronaldo on the six-yard line, with Isaksson given no chance. Sweden's resistance is broken!
A change for each side: Anders Svensson replaces Kallstrom in the Sweden midfield; Portugal send on Josue for Meireles.
Ronaldo booked for a challenge on Isaksson, who is hurt. Elmander is also cautioned for complaining on behalf of his stricken keeper. Isaksson eventually rises to his feet and is fit to continue.
Isaksson makes a stunning double save - in vain, as it turned out - to deny Ronaldo, whose flick from an offside position is parried by the Sweden keeper. Ronaldo has another go, after the whistle, but Isaksson gets up again to make a great block. Didn't matter, but great to see, nonetheless.
Larsson is booked for halting Coentrao's progress deep on the Portugal left. Ronaldo receives the free-kick short but he immediately gifts the ball back to Sweden before whining to the referee, who isn't interested in the captain's complaint.
Elmander superbly wins possession in midfield and releases Ibrahimovic. He lays off and immediately bursts into the box to attack a cross from the left, but Patricio springs from his line to claim the high delivery.
Nani spins on the edge of the Sweden box and drives in a left-footed shot which Isaksson fields well, diving to his left to gather in.
Bruno Alves thunders into the box in an attempt to meet a floated corner but his challenge on Elm is too strong for the referee, who awards Sweden a free-kick and a some brief respite.
Postiga's work is done, with Hugo Almeida sent on to lead the Portugal attack. His first contribution is to spot Coentrao's run but his reverese pass is overhit. A bright start, though.
Nani is given two attempts to cross from the right. The first effort is cut out at the near post; the second is skewed horribly behind the goal. Frustrating for Portugal.
Brilliant defending from Antonsson to turn Moutinho's low ball behind for a corner, which is then headed narrowly over by Postiga. Portugal well on top.
Another spell of Portugal pressure results in Meireles finding space 30 yards from goal. The former Chelsea and Liverpool midfielder goes for goal himself and immediately apologises after his drive flies over the bar.
Pereira gets forward once more but, for once, his delivery is poor, with Isaksson happy to watch the ball drift beyond the crossbar.
Moutinho's fine pass switches the play to Coentrao, whose first touch allows Sweden to recover and eventually clear as the left-back cuts inside. A lovely spot from Moutinho and a delightful pass.
Moutinho overlaps on the right before driving across an inviting ball, but no Portuguese attacker makes an attempt to get towards either post and the ball drifts out for a goal kick.
Nani whips in a dangerous low cross which Postiga diverts high and wide while under heavy pressure from Nillson. Portugal have restarted on the front foot and Sweden are having trouble getting out of their own half.
Chaos in the Sweden box. Bruno Alves floats over a cross from the right which Olsson fails to clear. The ball hits Pepe before Isaksson lunges from his line to deny Postiga but his punch rebounds around the six-yard box before Sweden eventually hack clear. A let off for the visitors.
Sweden restart after half-time and Ibrahimovic's first contribution to the second period is to leave a mark on Pepe, who is not slow to hit the deck. Portugal want the Sweden captain booked but referee Rizzoli refuses to oblige.
The two best opportunities came in the opening six minutes, with Moutinho first unable to find the target from an acute angle after rounding Isaksson, before Elmander was narrowly off target when he stretched to reach Lustig's cross. Ronaldo and Ibra have yet to have their say, but you can have yours - get in touch via email firstname.lastname@example.org or Twitter @IanWatson1 and let me have you thoughts.
There is no time to be added after an action-packed first half. Sweden will likely be the happiest of the two sides but Portugal remain dangerous. Pereira has been a constant threat down the Portugal right, but the two main men, Ronaldo and Ibra have been unable to stamp their authority on an entertaining game.
The half closes with a period of Portuguese pressure, but all they create is a header from Pepe which is directed straight into the arms of Isaksson.
Larsson goes for goal but only finds touch after sending his shot over the bar. Ibrahimovic is not happy.
Pereira is cautioned for a challenge on Kacaniklic. Larsson stands over the free-kick on the left...
Postiga is almost in after taking Nani's pass superbly, but Antonsson recovers to clear. A few moments later, Postiga upsets Isaksson by leading with his studs in an attempt to reach Pereira's cross. The Sweden goalkeeper, though, clings on before making his protest.
Larsson gives away another corner when Coentrao looks to reach Ronaldo's delivery. Veloso's set-peice lands on the head of the Portugal captain, but his header under heavy pressure is high and wide.
Ibrahimovic is dumped on the floor after a particularly late and heavy challenge from Veloso, who is extremely lucky not to be cautioned. A sign of Portuguese frustration, perhaps.
Nani wants a free-kick on the Portugal right after a challenge from Olsson but the referee correctly waves away the winger's appeals.
A period of Portugal pressure results in Larsson turning behind another Pereira cross. The corner is again cleared out of the box, but only as far as Meireles, whose volley falls between Nani and Ronaldo but neither can turn the ball goalwards.
Meireles floats a delicious pass towards Ronaldo, who has drifted in behind. Antonsson, though, just gets a nick on the spinning ball which falls conveniently for Isaksson to grab.
Sweden are making their physical presence felt, with Moutinho and Pepe both on the receiving end of heavy challenges. Sweden have conceded eight fouls so far, compared to Portugal's three.
Isaksson dives forward to punch Nani's cross away before another delivery from the right is headed behind by Lustig. Ibrahimovic heads clear the corner but the ball is returned to Moutinho, who delivers another threatening cross which Sweden scramble clear. Panic stations at the back for Sweden.
Sweden win a free-kick on the edge of the Portugal box, which Ibrahimovic stands over. Larsson is also in attendance, but it is Kallstrom who has a go. The effort flies wide of the target, however.
Fine save from Patricio. Ibrahimovic's step-over on the edge of the Portugal box allows Larsson a shot but his left-footed attempt is parried around the post by the Portugal keeper.
Pereira gets in another cross from the right which is headed behind his own goal by Antonsson. Moutinho's corner is cleared as far as the edge of the box but Veloso's volley is skewed wide. Right-back Pereira is the main creative force for Portugal so far.
A sighter for Ronaldo. He wins a free-kick in a position just off-centre, 30 yards from goal, but his strike is blocked by the Sweden wall.
Kacaniklic takes a long pass brilliantly on the left but as he approaches the goal-line inside the 18-yard box, the Fulham man fluffs his lines and gives away a goal-kick.
Postiga turns Nilsson brilliantly on the edge of the Sweden box but the defender's team-mates get back to crowd out the home forward.
More joy for Pereira down the Portugal right but his low cross is gathered by the diving Isaksson in his six-yard box.
Patricio has to be quick off his line to gather up Ibrahimovic's flick on as Kacaniklic bursts through. Sweden not content just to defend here tonight.
More nervous moments in the Portugal defence as Pepe makes a hash of two attempted clearances, with Elm then firing a shot from distance which takes a deflection and goes behind for a corner. Portugal, though, deal with the set-piece at the near post and quickly clear their box. A breathless start in Lisbon.
Another great chance, this time for Sweden! Lustig bursts into the space on the right and delivers a curling cross, which Elmander stretches to divert narrowly wide of Patricio's far post.
Great chance for Portugal! Meireles plays through Moutinho, who goes around Isaksson, but the angle proves too tight and his shot hits the sidenetting.
Another dangerous cross from the right, this time from Pereira, results in Ronaldo challenging for a header on the six-yard line, but the Portugal captain just fails to reach the deflected delivery.
The hosts are immediately on the attack. Ronaldo's delightful flick plays in Coentrao on the left but his cut-back is behind any Portuguese attackers. Moutinho eventually collects on the right and he sends in a delightful volleyed cross which his team-mates fail to read and the ball drifts beyond the far post and out for a goal kick.
The two sides are lined up for the anthems. Portugal's is belted out, almost a capella, with a huge mural displayed around Estadio Da Luz. If that doesn't get the adrenaline pumping through the Portuguese side, nothing will.
Jerry from Margate has been in touch, and he makes a good point: 'Let's all hope that the Iberia/Scando battle of the talismen doesn't boil down to who can play the referee best. Heja Sverige!' Nicola Rizzoli is the man in the middle tonight. Let's hope that is the last reference you see of the Italian tonight.
Ronaldo and Zlatan warmed up for tonight by scoring hat-tricks for Real Madrid and PSG respectively. Tell me: which one of the two do you most want to see in Brazil next summer?
Robin Doran has been in touch via Twitter and it seems he is one of the few not to get carried away by the build up around Ronaldo and Zlatan: 'All this hype between Zlatan and Ronaldo can only mean one thing... it's got 0-0 draw written all over it.' I hope you're wrong, Robin, but I wouldn't completely rule out a stalemate. Sweden have never lost in Portugal and they will be desperate to take home a clean sheet.
Fancy a flutter? This is the latest from our friends at Sky Bet: Portugal are Sky Bet's 8/13 favourites to win this first leg while Sweden are 5/1 outsiders, with the draw priced at 14/5.

Now you have seen the two line-ups, who are you backing to take an advantage back to the Friends Arena in Solna next Tuesday? Let me have your views, before and during the match. You can email me email@example.com or find me on Twitter: @IanWatson1
The only British-based talent in the Portugal side is Manchester United winger Nani. Of course, Raul Meireles, Ronaldo and Helder Postiga have all plied their trade in the Premier League in the past, with wildly varying degrees of success.
Portugal coach Paulo Bento has named his XI: Patricio, J Pereira, Alves, Pepe, Coentrao, Veloso, Moutinho, Meireles, Nani, Ronaldo, Postiga.
Sweden coach Erik Hamsen has nemed five British-based players in his line-up: Mikel Lustig of Celtic; Sunderland's Sebastian Larsson; Alex Kacaniklic from Fulham; and Norwich pair Martin Olsson and Johan Elmander.
Sweden team: Isaksson, Lustig, Nilsson, Antonsson, Martin Olsson, Larsson, Elm, Kallstrom, Kacaniklic, Elmander, Ibrahimovic.
Of course, there will be 20 other players on the pitch come kick-off, and Sweden have named the side which Zlatan will lead out...
At stake is a place at the World Cup finals, which will be missing one of the world's most talismanic players - Cristiano Ronaldo or Zlatan Ibrahimovic. The two talismanic captains begin their two-legged contest tonight in Lisbon to ensure they are not the one who will be absent from the party in Brazil.
