Manchester United boss Louis van Gaal explained why he played Marouane Fellaini in attack, after the big Belgian was involved in two of the three goals against Cambridge United at Old Trafford on Wednesday night.
The former Everton midfielder was a nightmare for the away-side as he troubled Richard Money's team with his strength and aerial threat - like he did when he headed the ball down for Juan Mata's opener on the night and his deflected shot which found Van Persie to assist Marcos Rojo's goal.
James Wilson came off the bench in the second half to make it 3-0, and Van Gaal was pleased the tactics he used paid off for the Reds.
"With Fellaini, we have always also an attacking point through the air," van Gaal told MUTV.
"Cambridge have very tall players and we could score also in the air and not only along the floor. That was our game plan and he [Fellaini] confirmed that [his aerial prowess] again.
"I think we could have scored more goals. In the second half, we played a little bit more forward and I believe we created more chances. Robin van Persie had four possibilities so we could have scored more but I am very happy the first chance of the match, for Cambridge, was against the post."
