For Porto, this was always about putting in a better shift than the first leg, and saving face. After a 5-0 loss at home in the first leg, the damage has been done, the issue at Anfield was how to minimise it. It was going to be no easy ask, only once have Liverpool failed to score at home this season in all competitions.
Jurgen Klopp rang the changes, starts for Adam Lallana and Alberto Moreno, with the headline being a place on the bench for Mohammed Salah and as expected, Liverpool were on the front foot. Sadio Mane grazed the crossbar with a close range effort after 17 minutes. Mane was at it again on the half hour mark, from a James Milner pass, the Senegalese forward chested down and fired a shot which beat Iker Casillas in the Porto goal, but his effort came back off the base of the post.
Next to go close was Dejan Lovren, three minutes after Mane’s effort, once again it was Milner the provider, his free-kick was headed on by the Croatian defender onto the top of the net. Goalless at the break, the second leg was already better than the first for Porto.
The Portuguese league leaders barely threatened the Liverpool goal in the opening 45 minutes, but it took them six minutes of the restart to test Loris Karius, who had to get down to deny Abdul Majeed Waris from distance. Chances were few and far between in the second period, even as Salah came on, the Egyptian had a shot well blocked by Porto skipper Felipe, while at the other end, it took two Liverpool bodies to foil Oliver Torres.
The best attempt, though, came late on, as Reds substitute Danny Ings had a header superbly tipped aside by Casillas. Goalless it finished, Porto had saved some face, Liverpool meanwhile were heading for the last eight.
