Personally, I'd be happy with two solid midfielders. And I believe we won't be splashing all that money.
Carsley, Fernandes, AJ and McFadden are all players who a had a part in the play. We haven't replaced any of them. That's what makes us weaker. Cahill is somewhat injury prone, Anichebe has been at the olympics. So two more players we won't have available for the whole season.
The kids can play their roles, but it's not fair to lay the responsability on their shoulders.
We're not doomed, but we won't be progressing either.
