I do think that is a real problem, that he has no real position to speak of, he could he very handy in a few roles but he needs his manager to say "this is where I want you to play, this is where you will play from now on, lets work on what I want you to do in this role".
As for drifting in to deep when he was played as a striker in a few games, I seem to remember we could not make a forward pass for love nor money, so he took it upon himself to drop off and pick the ball up, we see lots of top strikers doing that kind of thing, Rooney does it all the time. and before it gets jumped on, no I am not calling Dyer a top striker or compating him to Rooney I am just saying tis not always a bad tihing for one of your front 2 to drop off deeper to pick up the ball.
Aye, but Martins is always coming deep as well. It's a hopeless partnership, imo, and I hope we don't play it too bloody often in future.
