This is bullshit, to be honest. Yes, the team has deficiencies, but it's not like it needs to be gutted. We've got a really young squad with a lot of experience and quality which needed one or two signings for the first team. Moyes had ample time and money over the summer to make any moves he might have wanted. Even considering we didn't sign two players, finishing fourth with this squad is pretty much unacceptable. De Gea, Rafa, Smalling, Rio, Evans, Vida, Evra, Fabio, Anderson, Valencia, Kagawa, Carrick, Nani, Fellaini, Rooney, Van Persie, Zaha, Adnad, Young, Hernandez, Welbeck - that's a very good squad. If he can't make the most of this squad, then it's on him.
There's no point moaning about needing to sign players when we're just 4 games in and the transfer window closed a few weeks ago. He had his chance to sign players (and presumably he was being backed financially), now he has to get on with it.
