This is my oppinion:
Man Utd won't win the Premiership again, because in the English First League history, no one could win the title for 4 years in row. Another vital thing is losing some great players, Tevez, Ronaldo. And thirdly, no offence, but Ferguson is an old lady, I mean he has a great experience, but he likes Owen more than Berbatov.
So Man Utd won't win the Premiership this year.
Liverpool was near the winning it last year, but Ronaldo and the whole squad helped Man Utd to win it.
I think Liverpool has the biggest chance to win it, I think this could be their year. They have a nice squad, an experienced Manager and the team is gelled, I can't see many reasons Liverpool can't win it.
Chelsea have a nice chance to win the event again. They strength the team very well, they are gelled, but I think the Manager doesn't know very much the team, so in the first half of the season, maybe we will expect to see Chelsea doing some embarrasing matches (maybe). Chelsea have a great chance to win the Premiership
Arsenal has no chance to win it. Absolutely no chance. They just sold Adebayor, if Fabregas leave too, Arsenal won't win the Premiership in the next years. I already see them in difficult for keeping their 4th position.
No one voted them, but I think Man City have a great chance to destroy every teams' hopes. Maybe not winning the league, but securing a CL place I see Man City for in this season. They really strength the team and I can't see why not to make a big surprise.
