I like the physical presence of Matri, he wins a lot of headers.
I am not convinced Mirko would offer the same.
Matri would win more headers, but Vucinic would, in general, link the play more.
Ideally Juve would keep Matri for his ability/willingness to stretch defences out with his running off the ball, as none of the other forwards really do that.
Tevez does to some extent, but I think it'd be better for him to be the player profiting from that space being opened rather than being the one doing the thankless running.
Hard to see Matri still being a Juve player at the end of this transfer window, though.
