We don't have a lot of options up front, so Conte hasn't had a great deal of choice this season; there are basically two target men on this team, Qtube's characteristics make him a bit of a tweener. Today, Conte obviously wanted a target man late in the game because we were having trouble breaking them down off the dribble, and needed to continue to have an aerial threat in the box for set pieces, crosses, etc., when Matri was subbed.
Conte is flipping out after nearly every goal we score these days, this is the most crucial time of the year. Did you see him celebrating in the stands with Storari last week? He's losing his mind every week, we're on the cusp of something very special, and it's great to see.
None of this means that Borriello will definitively be staying, nor does it mean that he was the one who orchestrated the transfer in the first place - especially given the fact that GM tried to acquire the player before Conte was our coach!
You have a problem with treating your beliefs and opinions as fact. You need to spend some time in the realm of science, where facts require some proof.
