Rooney is undoubtedly an overall player who can play anywhere. But, playing him out if position too often is probably not the best move van Gaal made.
Rooney is maybe the best striker, I have explained that already a lot of times. It is not that anybody isn't a good player in my selection. I have to look at where each player can make the biggest contribution. It's the composition which is more important than the individual player.
van Gaal is right on one thing, Rooney is the best striker that we have. But shouldn't he play in a position where he contributes more? Wasn't he more successful up front? If we didn't have good midfielders, perhaps it would be the best choice. But we have the likes of Ander Herrera, Juan Mata, Fellaini, Januzaj who are all top quality players.
