Attacking in numbers is not the same as playing 'nice football', as some people have said United play in this thread.
I agree, Moyes's tactics are often poor and unadventurous, but the transfers aren't really his fault (he carries maybe only a little bit of blame for them). The statement about strengthening CM isn't really valid, by the way, because, as Mike.'s already said, masking a weakness isn't the same as not having one. Even though Fergie didn't need one to win the league, it doesn't mean that the squad's good enough to the win the league. Essentially, Fergie's just left Moyes in a tricky situation by not luring a CM in with his reputation, since, as shown in Thiago's case, the manager's reputation can play a big part in persuading a player. It's like Mourinho's Inter, he managed to win the treble with them, but he left Ben?tez with an ageing squad which wasn't capable of doing it again.
