The thing is, Moyes didn't want to spend. It's not his M.O.
But the cash would have bene there as it was for his successors. Moyes was trying to prove a point that he could be a good little company man.
He started out with a squad where he could call upon
De Gea
Evra
Ferdinand
Vidic
Mata
Fellaini
Giggs
Carrick
Fletcher
Nani
Rooney
Hernandez
Van Persie
...to finish 7th with 25 points less than the previous season was a catastrophe for him.
There's no way you can polish a turd on this for Moyes. It's just not happening for you.
If
Moyes didn’t want to spend he wouldn’t have tried for Fabregas.
Moyes knew what the key issue was - the midfield problem.
The big irony of it all is Moyes had secured the key piece to get them back on track without totally rebuilding - Toni Kroos. LVG killing that transfer was a major blunder. In my opinion the problems at Man Utd didn’t require such drastic action, but a measured, quality focused evolution. It’s certainly the sort of approach Ferguson would have advocated for, and he knows a fair bit about the sport.
Man Utd always had good players, but they were always about being more than the sum of their parts. They turned into Real Madrid lite.
It worked out well in the end as Man Utd have been completely humbled and could well end up a financial casualty.
