Liverpool are 90 minutes away from qualifying for the UEFA Champions League's last four in back-to-back seasons after they beat Porto 2-0 in the opening leg of their quarter-final meeting on Tuesday.
Naby Keita sent Anfield into raptures after his deflected effort unlocked Porto's defence five minutes in, and Roberto Firmino was positioned well to slot home a second before the half-hour mark.
The hosts couldn't add to their tally in the second half, but a home clean sheet ahead of next week's visit to the Estadio Do Dragao will please manager Jurgen Klopp.
Keita Catching Fire at Exactly the Right Time
Four days after scoring his first goal for Liverpool in a 3-1 victory at Southampton, Keita doubled up with his first strike in front of an Anfield crowd.
