Gylfi is nowhere near good enough to be deserving of having the team shaped around him.I agree he could be useful for us if we move towards having a 10. Having decent CMs who take the pressure of Gylfi might allow him to stay in forward areas where he can be effective. Having him sit deep is just a nightmare though.
This is a good point too, he's definitely more of a second striker. A number 10 that doesn't go looking to pick up the ball in space and has a complete lack of dribbling ability isn't what I'd consider a number 10.The problem with Sigurdsson anywhere near a 10 is that he ISN'T a 10. You look at their average position at the end of a match, Glyfi is almost always the one most forward. He's not supplying opportunities for the peolpe in front of him, he's the one looking to score. That's not a 10.
