What's wrong with you? I also said half a season doesn't justify enough for a whole season, especially when that good part is the shorter one, right there in that post you quoted. I reiterate, 1/4 of something doesn't make up for 3/4.
It's needed to compare them. Amauri played the past year and a half, completelly off-form while leaving the better striker on the bench. Especially in 2008/2009 when Trez needed games to regain match fitness after surgery on both knees. He was consistently overlooked by Ranieri. That continued in 2009/2010, where Trez again, only needed matches...if he just played a few more games instead of Amauri, he would have regained his form and scored even more goals.
When an off-form player plays, that is wrong and that's the bottom line. It was wrong when Ibrahimovic was benching DP in his second season, it's wrong now with Amauri and Trez, hell even Iaquinta. I just hope Del Neri rotates more, Trezeguet needs little to show his worth, whereas Amauri needs a lot.
