I just don't think we need a midfield playmaker, and I don't think Wenger will go down that route again. He adapted the team to play that way because Fabregas was a genius, a one off, he won't do that again - it's not his style in my opinion.
I think he wants a solid, strong and athletic midfield, with genuine speed, danger and productivity from the forwards. I think that's the way we will look to build.
If M'Vila is strong, quick, athletic, a reliable quick passer of the ball, who has good understanding of the defensive side of the game, as I'm led to believe he is - he will fit nicely into that system.
