Chuck a big cf in there, & maybe sign another striker as backup then John Terry for example, next to Smalling, sign one really talented centre mid & Mourinho could make a competitive team out of the rest imo. Not a great football team, but a results team, baring in mind how many clubs usually go to pieces as soon as they see the shirts. It was enough for Ferguson to retire with a title against vastly superior teams (such as us) They will be able to offload their shite for twice what we would get, plus a load of the shit kids they have used, as they have played Premier League football & the rag bullshit factor plus all the ex rag managers, lovers, etc will help.
It will be very difficult for them to ever become the 'glamour' team ahead of clubs like City I think, but imo it's easy enough for them to become competitive. But only 'if' they get the right manager & he gets the balance right.
Big call coming up. Get it wrong & they could become Liverpool.
