I'll agree that the lack of cover for someone like Carrick is a problem, particularly if he gets injured and we've got someone like City coming up. I've been dying for us to sign Martinez all summer because of this, but I just think it's worth taking into consideration that signing someone now after the signings of Kagawa and Van Persie could seriously disrupt things.
This midfield situation over the last few years...it really has been so weird. You wouldn't think signing one would be so complex an issue. Between waiting for players to emerge, remaining rigid in having 2 central midfielders/an insistence on width and, in line with the above point, trying to keep everyone happy, it seems the most frustrating little episode. You can understand Fergie's hesitance to strengthen, and you can also understand the worries of people who feel we need cover for Carrick, but it's surely a bit difficult to know how to proceed at this point. If we do get cover for Carrick, you'd think that player would have to be good enough to start. If he is good enough to start, he'll drastically reduce Scholes, Cleverley and Anderson's playing time (we're not going to sign someone good enough for the first team and not play him) unless we then revert to playing 3 central midfielders. If we do this however, we then limit ourselves to 3 of Van Persie, Rooney, Nani, Valencia, Welbeck, Hernandez, Young and Kagawa. Quite simply, the repercussions throughout the squad are vast. This is before going on to discuss what it does to the chances of players like Powell, Petrucci, Lingard, Daehli, Januzaj, Tunnicliffe, Henriquez, Keane etc in the future.
Of course it's not as simple as this, but there is a limit to how much players can be rotated and kept happy you'd think, not to mention that it is actually wise to maintain some semblance of an idea as to what our best team is (or just some consistency in general). The most pressing concern for me is that it would seem such an incredible waste at this point not to fully bring through the likes of Cleverley and Welbeck, but there's a chance this is exactly what signing a midfielder would entail. On the other hand, if we do lose Carrick and have to go up against City/Barcelona/Madrid, there's an equally good chance that we'd be fecked.
Ahhh....

Edit: I don't even know what my stance on this is now, to be honest. I said up there that if it's not a top class midfielder we shouldn't bother, but I think this post is more verging towards the stance that a midfielder now wouldn't be a good idea. Don't get me wrong though - if we had signed, say, someone of Martinez's quality and ilk, we'd have a team and squad almost entirely without weakness! It's just that signing anyone now who is, say, under the age of about 28, would potentially feck a lot of shit up. It may even make us more successful, but it'd perhaps end up being most 'un-Unitedish' if you get me.
