Depends - as a sitting midfielder I've thought in the past that he doesn't really have the required positional sense to play as a proper holding midfielder - he tends to be at his best when he can go hunting the ball.
He's done that holding role well enough in a few home games this season against lesser sides, but I'm yet to be convinced he's the answer long-term there, although I like him a lot as a player
Think the interest in N'Zonzi and links to Amadou suggest that we were looking for someone who plays that role more naturally and who uses the ball a bit better than Gueye does and I have to say I think that when the summer comes and we (hopefully) get rid of Schneiderlin, we need to look at a proper holding player, ideally someone with physical presence, and someone else with a bit of creativity as Rooney won't be able to play every game in midfield next season - someone like Seri from Nice (though he would probably have better options than us)
