Watching the game yesterday, and i know this will probably be an unpopular statement, but I'm not sure it isn't Sig that isn't a large part of the problem of know.I don't think he is a no ten tbh
I watched him closely and for a number 10 he doesn't get close to the striker, or the opposition box, anywhere near as often as he should in that position.
It feels like we play with a midfield three and a striker a lot of the time which means it looks disjointed. Even when he's playing off the left he doesn't take up positions that hurt the opposition, he's often a Mirallas-lite, making runs across the defence.
I'm not sure what the answer is but for £45m I want him affecting the play a lot more.
He works tirelessly and would be decent in a three mf
