Do they?....plus Ferguson's side used to try and rough us up a bit and that's fine but there is a difference between that and sticking 11 men behind the ball and then whinging when smaller sides come to you and do it. To be fair, I used to get annoyed with Wenger when we dropped points at home and bemoaned smaller sides playing for a draw. If in terms of resources you can't compete in terms of football, setting up for a clean sheet is understandable and acceptable. For a team like Chelsea, whilst I can understand them playing that way against Barcelona...a team like Atletico Madrid who have far less than them in terms of financial resources its pretty depressing.
Than again I think the 0-0 wasn't so much about a Mourinho masterclass, it was exposing the limitations of players like Diego Costa....I hope Chelsea do sign him because I think he's overrated....one season wonder like Diego Tristan at Deportivo.
