Why couldnt they. Man Utd got rid of Ronaldo. Liverpool got rid of Alonso. Arsenal sold Toure and Adebayor. Man City bought a brand new team with too many strikers and will need to gel. Chelsea have an extremely settled squad and ran Man Utd close last season.
I suspect Chelsea will give Man Utd a run for their title this season simply due to depth of their squad and how many quality players they bring in if one or two of their primary players are out injured.
yer well u was in with a brilliant chance of winning the league last year also in the fa cup and the champions league but. u crashed out of both cups. its a fact that liverpool havent got the best squad simple as that.
