That the Serie-A is weak is a great exaggeration. The image of the league took another huge blow when we crashed out of the CL, undoubtedly, but keep in mind that squads such as Inter's and Milan's are struggling in this league (they have many players that are very good), and that Napoli beat Arsenal - current Premier League leaders - in this season's CL. Tevez, in his most recent interview, says that it's the most difficult league he's ever played in.
The EPL has more quality overall, but Serie-A is still a very difficult league and the difference isn't as great as your ordinary "Goal.com" poster and the english media would have you believe.
