He still managed to spend nearly £400m. That's the problem with Mourinho, he won't develop young players so you need big pockets for him be manager as he wants to buy already established players.
Woodward's reign's been a mess on the pitch though, it's all very well tying up big sponsorship deals but if the club's not doing it on the pitch then those deals will soon dry up. No matter what you think of Moyes he was let down badly by Woodward and it's been a bit of a mess ever since even with a couple of early trophies for Mourinho, Woodward needs to take a big part of the responsibility.
Neville even said himself for years loads of teams outspent United but their structure was more in tuned to win.
Still, the pochetino shouts make sense as he would still do better with that group of players than Mourinho ever did because he is a better player coach.
The whole backroom staff have been a shambles though since Ferguson left. It's a massive part of why it's going wrong there IMO.
