Liverpool scored twice in the first half to beat FC Porto 2-0 in their Champions League quarterfinal first-leg match at Anfield on Tuesday.
Porto exited the Champions League 5-0 on aggregate to Liverpool in the round of 16 last season and the hosts picked up where they left off in that tie when Naby Keita opened the scoring inside of five minutes courtesy of a deflection that left Iker Casillas no chance.
Jordan Henderson the split open the Porto defence for Liverpool's second, springing Trent Alexander-Arnold who squared to Roberto Firmino for the easiest of finishes to make it 2-0.
Porto had two chances for a precious away goal around the 30-minute mark, but Alisson saved both attempts from Moussa Marega either side of VAR denying the visitors' penalty shouts for handball on Alexander-Arnold.
Sadio Mane had the ball in the net for Liverpool's third soon after the restart, but the line judge rightly had the flag up for offside and the goal was ruled out.
The Senegal international saw a good effort go just wide in the 70th minute when his curling shot from outside the penalty area sailed past Casillas' far post, as Mane made way for Divock Origi soon after.
Porto pushed for the away goal, but Liverpool's defence held firm for the clean sheet ahead of the return leg in Portugal on April 17.
