Liverpool built up a healthy first-leg lead over a visiting Porto side at Anfield, as the two teams engaged in battle in the Champions League quarter-final stage.
Jurgen Klopp’s side needed only five minutes to break the deadlock, as the ball fell to Naby Keita on the edge of the area and his heavily deflected effort looped up and over Iker Casillas.
