Rooney is our best no 10 hands down, the rest are pretty much useless imo.

Rooney has the best vision, best shot, and makes the most of possession. The problem with Rooney is that he seems to play with lead in his boots these days, back when he played no 10 in 2011, 2012 and 2013, he was still an explosive and dynamic player who could pick out passes and score goals combined with good defensive awareness. He isn't as mobile these days but he is still more effective than Mata and Herrera.

Mata- He is so small and weak, any decent opposition player will just kick him all game and render him invisible, also without runners ahead of him he is even more less effective.

Herrera- Sometimes has a great game but doesn't go enough consistently, hence he is always dropped by LVG at some point. I prefer him more in a deeper midfield role anyway.

Fellaini- Just makes me depressed seeing him play in the no10 role, but he can be effective higher up when he is used as a literall battering ram, opposition defenders can't keep up with him on his day. Not a very good "footballer" though.
