Marouane Fellaini has said that Manchester United must beat Arsenal at Old Trafford on Monday evening and avoid a replay.
United boss Louis van Gaal will host the cup holders in the quarter-finals on Monday and battle it out for a place in the semi-finals and a trip to Wembley.
Fellaini has had a good run of form recently and he has spoken of the importance in not playing a replay at the Emirates.
The Belgian international told The Express: “It will be a challenge. Monday is a massive game.
“We have to win it in one game because playing at Arsenal would be difficult. The FA Cup is a special competition, a big trophy in England.
“I lost a final. I played in a semi-final. This season, I can win [it]. We have showed [spirit] already a lot of times now and we have to continue like that.”
