LIVERPOOL, Feb 15 — Mohamed Salah struck as Liverpool cruised into the FA Cup fifth round with a 3-0 win over Brighton on yesterday, while Marc Guehi scored his first goal for Manchester City in a 2-0 victory over fourth-tier Salford.

Brighton had beaten Manchester United in round three, but the Seagulls have been in miserable form since and were easily beaten by an improving Liverpool at Anfield.
