I think it was right to let Rio, Vidic and Evra go, they where all over the top. The problem is that we still have to many avrage players like Fletcher, Cleverly, Young, Valencia and Fellaini. It's just too many of them, and they are to often involved. Fletcher is in his last year of contract and we owe him as much as keeping him the last season, but Young, Valencia and Fellaini should be sold and replaced at once.
I think we should have kept Nani and payed over the top for Vidal and Di Maria, then we whould have been in a situtation where only small changes had to be made year by year.
