Barcelona put one foot firmly in the semi-finals with a convincing win over opponents Roma at the Nou Camp.
The Italians will feel unfortunate to have lost by that scoreline, having given Barca a two-goal lead after scoring two own goals.
First Daniele De Rossi poked the ball past Roma keeper Alisson into his own net after he thwarted Lionel Messi when through on goal.
Kostas Manolas then played the ball off his own post before it ricocheted back off himself and into the net for 2-0.
Gerard Pique swiftly added a third from close range as Roma's hopes were sinking without trace.
Edin Dzeko gave them a lifeline with a crucial away goal but Luis Suarez restored the Catalans three-goal advantage to take into the second leg.
