I don't care if he's 24, 27, or 30, if Di Vaio is involved in any swap deals (Cannavaro perhaps) I'd love to have Heinz as a back-up striker. The chances of signing Gilardino now seem extremely remote, and well, Heinz has shown that he's quality.
He is a very gifted player, but his stamina lasts only for about 40 minutes, and he lacks speed and acceleration. I watched him against germany live, he was awesome in the first period, and unrecognizable in the second.
