Defensive midfielder is not the position in hand, central midfielder is. For the past two seasons we have undoubtably had the best defense in England, and I really dont understand why we would spend a fortune at Rodwell, because we are not talking about a man that will arrive for little money. Defensive midfielder is only needed against clubs with great attacking midfielders, meaning we really dont need one most games, Fletcher is one of the best in the world at that position, and I think he only gets better and better.
If we were to sign a midfielder we need someone that will improve our attack, not our defense. Cleverley can play central in a 4-4-2 against most opponentes. I think the clue is, get him as much Premier League experience as possible. If we were to loan him to Bolton, it would have to be under the garantee that he would be a starter. I think Cleverley is a man for the future, Rodwell would mean less playingtime and that would not be a good thing. If we sign Rodwell and lend Cleverley to Bolton could be ok though, Wilshere florished under his spell there.
