Chelsea have the problem that Roman expects to win everything every year and this causes problems as the team doesn't have time to gel and a manager cant make a mistake otherwise they get sacked. It's the same boat as city are now in, the only diffrence is that since Roman has taken over we have won titles and with Chelsea being in the Champions League it makes it easier to attrack the big name players.
I honestly dont think Arsenal will win everything if they contiune with this youth player only thing and they need to by some good players no matter there age (there best players this season was Archavin who is 27).
If Man utd lose Ronaldo (not gonna belive he is going till I see him at his new club signing with there scarf over his head) they will replace him, probley with Ribery from bayer. Tevez may be a loss but they ahve won plenty of games without him and they will either by him or replace him and I think they will be near the mark agian

.
Liverpool may win a cup or two but I dont think they will win the League they always find a way to throw it away or they are always to far behind when they start there charge.
Chelsea probley needs a bit of clear out and some new players and they will be in the running for every title, it will be a question of can they keep there heads which will depend on how many they win (A Champions League would be f..king nice!!!!). thats the top 4 thoughts for the moment.
