A rare goal by Thiago Alcantara and the customary one from Mo Salah was enough to maintain Liverpool’s 100 per cent record in this season’s Champions League - an achievement matched only by Bayern Munich and Ajax.
Porto had chances to cause an upset at Anfield but were undone early in the second half when Thiago grabbed his first goal of the season with a stunning half-volley from 25 yards.
In contrast, Salah’s scoring contribution was entirely expected as he kept up his current goal-a-game ratio before he was withdrawn by Jurgen Klopp to save him for bigger battles ahead.
