Ivan Toney's double eased Brentford to a 2-0 win over Sky Bet Championship new boys Coventry City.
The Bees' summer signing struck twice in nine second-half minutes to seal the points before leaving the field with what looked like a shoulder injury.
His first came less than a minute after half time when he ghosted in between defender and keeper to poke home Bryan Mbeumo's right wing cross after a slip by defender Ryan Giles.
The big striker grabbed his fifth in as many games less than 10 minutes later when he headed home Emiliano Marcondes' precision cross at the far post to leave City with a mountain to climb.
Toney always looked lively and was the first to test City's resolve with a neat shot on the turn from the edge of the area inside the first minute, which Marko Marosi saved.
Brentford laid siege to the Sky Blues goal in the opening minutes, Henrik Dalsgaard and Sergi Canos seeing long-range efforts deflected wide.
They almost broke the deadlock on 10 minutes when Canos' first-time cross from the left was met by Marcondes, whose looping header found the roof of the net.
Coventry, without suspended playmaker Gus Hamer, looked shell-shocked for the opening 20 minutes as they struggled to find a foothold in the game.
Brentford were passing and moving the Championship newcomers off the park, without really creating anything clear-cut in front of goal.
Toney asked questions again midway through the half with a blistering half-volley brilliantly tipped wide by Marosi at full stretch.
Coventry's first attempt on target came on 38 minutes, Michael Rose arriving late and unmarked at the far post to meet Giles' free kick only to slice wide.
Mark Robins' side began to grow in confidence as the first half wore on, their well-drilled back five reducing the Bees to speculative long-range efforts.
But the disastrous start to the second spell left them powerless as Brentford turned the screw and contained their lively visitors to see out the game.
They had a let off on 67 minutes when David Raya's punched clearance fell for Matt Godden 12 yards out, only for his acrobatic volley to bounce down off the bar.
Godden reminded the Londoners it was far from over minutes later when his instinctive near post effort was gathered safely by Raya.
Brentford managed the game well in the dying minutes, but it took a point blank Raya stop from Godden's header late on to keep the clean sheet intact.
Ben Sheaf might have done better with an injury-time effort on goal when the ball sat up nicely but he fired straight at Raya.
Godden, a bright spark for the Sky Blues, refused to give up the ghost and fired in a low drive which again found only the gloves of the Spanish goalkeeper.
But in the end it was a comfortable afternoon's work for the Bees, who proved there is life after Said Benrahma following his departure to West Ham.
What the managers said...
Brentford's Thomas Frank: "We were good for 75 minutes and really good in spells. We started the game fast and dominated from the first second, but in the last 15 or 20 minutes we needed to do better.
"We got the first goal early after half time and that was down to our patience, persistence and determination to keep playing at a high tempo, so I am pleased with that."
Coventry's Mark Robins: "We are clearly a team just promoted and trying to find our feet. The level we've come into is a huge step up so I just want us to show our real face because we are good.
"The last third of the game was more us and we started to have a bit of confidence but we have to do that when there is something to lose because this is a tough, tough league."
