I admit that some people here do hate Zlatan because he keeps DP out of the team but I don't fall into the category.
As for Trezeguet, he has been invisible but I would leave him on the pitch for the sole reason that he's our best finisher. Now that I come to think of it, DP could come on for Trez too though because recently DP and Zlatan have formed a more productive partnership than DP-Trez.
It's a bit difficult to sub Trez, seeing as he's scored nine in nine. Also on juventus.it he announced his intention to equal Batistuta, his idol, to score in 11 games consecutively
