His form has been on the decline towards the end of last season. Lets not kid ourselves about that. Yeah, he was injured, but some of the chances he missed in the latter part of the league last season were the ones he'd generally score with a blindfold.
That said, he'll come good this season, but it will take time. On pre-season form alone Amauri will get the nod ahead of Trezeguet. That doesn't mean Trez is useless or needs to be sold. The only thing I expect from him in the beginning of the season is that he doesn't feel disheartened if Amauri is on the team sheet ahead of him. Once he scores his first couple, he's gonna start firing on all cylinders... If this team has to win silverware with the resources we have right now, then we should have all four forwards in form. It's the variety they offer and Diego that will make all the difference this term...
