Gamesmanship

Should it be allowed?

Certainly don't make yourself any friends doing it!

As far as i'm concerned any advantage without actually cheating is fair game, No different than defenders whispering in the forwards ears trying to get a reaction or vice versa, Imagine Fellaini doing that with his hair lol

Fellaini is a funny fella at the minute, not sure whats happening with him and the Everton fans.
They were booing him the other day, against Wigan, although his attitude did look a little suspect during the game.
Stormed off after being substituted too. Probably didn't help a few weeks back when he said he wanted to join Chelsea
