Pato is very much still in 'adjustment' mode to Leonardo's tactics. I agree with Samaldinho, he has all the characteristics to play like a second striker, ala Sheva in his younger days, but his youth and inexperience are showing. He doesnt pass when he should and dribbles when he shouldnt. And really with R80 and Seedorf interchanging, it is difficult for him to get used to the AM that he's supposed to link with. Give the kid some time, he will be awesome, there is no doubt.
As for fullbacks, I still dont know why everyone is still crying out for a good right back. Guys, it is the left back position that we need. If Zambro gets injured, who's our left back? No one except for Janku or Favalli, which is a disaster. If our right back (again Zambro
) gets injured, we have plenty of options---Oddo, Abate, even Flamini. I'm sure Galliani knows this, otherwise he wouldnt have bid for Cissokho (who is a left back) in teh first place.
