Nah, I'm one of the few who still praises the squad and their abilities. Certainly a better squad than Tottenham or Everton. Most of the problems stem from Moyes & his staff - he's taken the team that outscored everyone last season and so far has erased 30 goals (United scored 86 last, currently on 56). You can claim a team is under performing up front when they create chances and can't score, but Moyes teams rarely create chances in the first place. He's managed to do that with his set ups and tactics - every month was a new tactical disaster. You mention Rooney, well personally for me he should have featured less. For example at Everton, the match screamed for someone like Welbeck or Chicarito to be stretching the forward play and that's exactly what Rooney wasn't doing.
A few signings that beef up the back line, a midfielder is always welcome and a new face somewhere, anywhere. And probably a new young forward considering the previous Welbeck & Chicarito have both signalled for departure.. which in itself is maddening - I love those two. I just hope Moyes doesn't do more damage in the transfer window before his time is up.
