Decent post, the sales should hopefully compensate for the loss in Champions League money.
I think in terms of signing the midfield play maker everyone is crying out for, it's not going to happen. Fergie will look at Scholes and Giggs and see that he can 40 - 45 quality games out of them two. In which that time we should hopefully be able to give Anderson, Cleverley, Fletcher the games needed ti improve and prove their fitness. Carrick will give that dependency and then there is Jones and Park along with Pogba who can offer cover in the middle.
When Scholes and Giggs leave it is my opinion that between Carrick, Fletcher, Cleverley and Anderson we will find our midfield two and with Pogba providing back up we'll be well covered. It is only when Rio, Carrick, Park, Vidic and Evra leave (Jones will operate in defence more so won't be an option in the middle) that we may see an additional signing for the middle come in as at that time we will have Anderson, Cleverley, Fletcher and Pogba just in the centre. We are talking at least two seasons here but if everything goes well I don't think we'll sign anyone.
Unless something happens Anderson doesn't become a regular or Pogba moves then we might see someone come in before that. I actually thought that with the Gibson transfer it sort of opened the door for Rodwell to come in. I think Fergie likes him and he could give us an extra option in centre back and the middle of the park but we'll see.
There are a few players who I think could be added to the squad but they are majorly unrealistic, I think that a player like Bale for the left wing, Sturridge for attack and Wilshire for the ball player would really improve us. But these signings are not available so we will work with what we have.
