Barcelona took control of their Champions League quarter-final with Roma, rolling over the Giallorossi 4-1 in Tuesday’s first leg.
A brace of own goals gave Barca the lead, before Gerard Pique and Luis Suarez made it a pair of big Spanish victories over Italian opposition in the last eight, despite Edin Dzeko's late consolation.
Nelson Semedo and Sergio Busquets were back for the Catalans against Roma, who took to Camp Nou without midfield general Radja Nainggolan and man-of-the-moment Cengiz Under up top.
Barca got their chances in early but were denied by the post after Ivan Rakitic's low cross-shot had flown past Alisson between the Giallorossi's sticks.
Daniele De Rossi was last man for a crucial tackle on Luis Messi, before Alisson got down quickly to palm Suarez's angled drive away from both the goal and Sergi Roberto.
Kostas Manolas pinched the ball off Messi’s foot as he was pulling the trigger from 12 yards, but when the Blaugrana did break the deadlock, it was through a moment of luck.
Indeed, Andres Iniesta’s through ball was on its way to Messi when De Rossi intercepted at full-stretch – accidentally prodding it past his own goalkeeper.
Roma could’ve equalised within 20 seconds of the restart as Alessandro Florenzi’s cross found the head of Diego Perotti, who steered it wide from close range.
Moments later, Alisson parried a Jordi Alba attempt and Suarez turned the rebound over, but Florenzi caught Umtiti napping in the six-yard box and hit the post after the ball had been dragged out of play.
Nonetheless, Samuel Umtiti managed to get on to the end of a cross from the right and hit the post from five yards, before the ball ricocheted into the net off Kostas Manolas for a second own goal.
Remarkably, that was the fifth own goal Barca had benefited from in the Champions League this season, with only Messi proving more prolific.
A third goal for the hosts soon followed as Gerard Pique was quicker to react than Federico Fazio, tapping in a rebound from six yards.
Marc-Andre ter Stegen, meanwhile, pulled off two stunning saves, instinctively keeping out Gregoire Defrel's half-volley after he ran into trouble, before reflexing to tip Diego Perotti's piledriver over the bar.
Roma did manage to pull one back, but not until 10 minutes left, as Stephan El Shaarawy let Perotti’s pass through for Dzeko, whose first touch took it away from Jordi Alba to score from 12 yards.
However, Maxime Gonalons gifted Suarez his first Champions League goal of the season with an appalling first touch, setting up the Uruguayan to score from 10 yards.
The Lupi pushed for a second goal right at the death, but Aleksandar Kolarov’s free kick skimmed the bar.
