Would be a concern not just in terms of quality, but quantity as well. Our 4 senior CMs would be Carrick, Fletcher, Anderson and Giggs. Fletch has long term fitness questions going into the season, Giggs is 37, and Anderson has a long history of injuries. 4 is quite a low number anyway when you consider it's probably the most taxing position. I suppose it would mean Park playing centrally more often. Edit- forgot about Cleverley, but hoping for a breakthrough from him would be a bit of an Arsenal thing to do.
But I won't be judging until the transfer window shuts. SAF is hardly a beacon of truth when talking to the media, it could just be a negotiation tactic, or as DF says a way of avoiding a 'failed' summer. If he says 'we are desperate to sign a CM', and then we're unable to find one we want, it sends a negative message to the supporters and the players and a positive one to our opposition.
