Manchester United manager Louis van Gaal has declared himself "reasonably satisfied" with his side's 3-1 win away at Preston North End in the FA Cup fifth-round clash at Deepdale.

Scott Laird fired the hosts into the lead in the second half, but strikes from Ander Herrera and Marouane Fellaini, plus a penalty from Wayne Rooney, gave the Red Devils the win.

Van Gaal told BBC Sport after the game: "I was reasonably satisfied. We didn't give anything away. The Preston goal was a little bit unlucky, it was deviated.

"But then we showed an unbelievable team spirit. We changed the shape and that was the solution. We scored fantastic goals, a little bit lucky also I think. I liked the second goal a lot, we have trained that a lot.

"Marouane Fellaini has a body, he also scores goals. I played him in the position that he wants for the first time but I do not always have a position for him. The spirit was better."

United will host Arsenal in the quarter-finals of the competition.
