Chocholate.......
I can only imagine that you are looking at it all wrong...
We play 2 CM players in Rodwell and Fellani who both tend to miss a high amount of games. Are options to cover them has been 2 CB's all season. whilst not a world beater by any stretch Gibson for a very low fee can play there when needed.
I don't think in any way he would be signed as the replacement for Arteta or because moyes thinks he's what were missing but even being skint we still need squad players. Especially when they come up at low fees.
Barkley is a ACM playmaker type player who will play off the front man not a deep CM type player from what I can see, so it wouldn't hamper or delay his inclusion.
We need a striker and creative midfielder and his signing would not be to solve either but we need to add cheap squad players in a few possistions where we can also.
You need to look at it for what it is mate...
