(Reuters) - Liverpool's easy Europa League win over Sparta Prague meant that they could already begin to focus on this weekend's FA Cup quarter-final with Manchester United during that game, manager Juergen Klopp said on Friday.

Klopp's side were 5-1 up from the away leg and on Thursday they raced into a 4-0 lead after 14 minutes, with qualification to the quarter-finals secured. In the end Liverpool won 6-1 and 11-2 on aggregate.
