Messi and Ronaldo spot-kicks ensure El Clasico ends all square
Penalties from Lionel Messi and Cristiano Ronaldo ensured the first of four El Clasicos in coming days ended all square in the Santiago Bernabeu.
After a goalless first period, Raul Albiol was sent off for hauling David Villa down in the box and Messi slotted away the subsequent spot-kick on 53 minutes.
But Ronaldo rescued a point for Jose Mourinho's side with eight minutes remaining after Marcelo was fouled by Dani Alves in the box.
Ronaldo's equaliser could prove a crucial morale booster for Madrid ahead of Wednesday's Copa del Rey final and their subsequent UEFA Champions League semi-finals against the Catalan giants, but this result leaves Barca within touching distance of the Primera Liga title.
They remain eight points clear with only six games left, while they also boast the better head-to-head record against Madrid having won 5-0 at the Camp Nou earlier this season.
There were surprises in both starting line-ups, with Mourinho selecting centre-back Pepe in midfield and dropping Mesut Ozil to the bench, while Carles Puyol was brought straight back in for Barca after three months out through injury.
Puyol had not been expected to be fit until next week's Copa del Rey final, but his return was a huge boost for Barca, whose four defeats this season have been without their skipper on the pitch.
Quiet start
After a quiet start to the match, Barca soon settled into their slick passing game and they fashioned the first clear chance in the 19th minute.
Andres Iniesta's pass over the top picked out Messi's run in behind the Madrid defence, but the Argentinean's attempted lob over Iker Casillas was saved by the Spain custodian.
Madrid responded to that with two efforts of their own, Barca goalkeeper Victor Valdes fumbling Karim Benzema's shot just wide of the post before Ronaldo headed a corner over from six yards out.
Barca then had a huge shout for a penalty turned down in the 27th minute after Villa beat Casillas to a Messi through-ball and went tumbling over his Spain team-mate's challenge.
However, referee Cesar Muniz Fernandez deemed there to be no foul, much to the astonishment and anger of the Barca players.
The first half would end up finishing goalless, although both teams fashioned great chances to break the deadlock in the minutes leading up the interval.
Firstly, a good Barca move set up a shooting opportunity for Messi which Casillas did well to beat away, then moments later at the other end an unmarked Ronaldo looked certain to score following a corner but his close-range header was cleared off the line by Adriano.
That was an exciting end to an evenly-matched first period, and the second half started off in much the same vein.
Hit post
Ronaldo came within inches of putting Madrid ahead in the 49th minute when his 25-yard free-kick smashed against the foot of Valdes' right-hand post with the Barca keeper beaten.
However, two minutes after that let-off Barca took the lead in an incident that also Madrid reduced to 10 men.
Villa was dragged to the ground by Albiol as the two tussled for a through-ball, and this time Muniz Fernandez had no doubts as he pointed to the spot and issued last-man Albiol with a red card.
That gave Messi the chance to score his 49th goal of a record-breaking season in all competitions, and the Argentina forward duly obliged, firing his penalty high into the Madrid net.
Barca suffered a blow soon after that when Puyol was carried off injured on a stretcher, but that did not seem to affect the visitors too much and Xavi almost made it 2-0 in the 61st minute when his shot clipped the top of the Madrid crossbar.
Despite playing with a man less, Madrid still created chances and Angel Di Maria blazed one opening over before Pepe failed to convert a clear opening at the far post following a corner.
With time running out Barca looked on course to equal the record of six successive Clasico victories, set by Madrid in the 1960s.
However, Madrid continued to fight and they were rewarded with a penalty following a challenge by Alves on his fellow Brazilian Marcelo in the area.
Barca protested but, after their appeals had been turned down, Ronaldo coolly stepped up to send Valdes the wrong way and earn Madrid a morale-boosting draw - even if the result means Barca remain firmly on course for a third successive league title.
