He's not growing weak, just bored and frustrated. It's really hard watching this Juve, particularly when teams of the past had players one could actually fall in love with seamlessly, the likes of Zidane, Davids, and Baggio spring to mind. I really dislike or am indifferent to say the least, to 70% of our current squad. The only players that I actually admire and respect are Buffon, Chiellini, Melo, Krasic, and Del Piero.
We still have a chance to get 4'th though, if we win our next two games, and Lazio lose to both us and Inter.
