Benteke's hold up play along the floor would be good, he can hold up the play along the floor like Berbatov. He's not just a knockdown merchant. Right now we are playing the ball to Soldado and it is going straight back downfield. Benteke gives us an option of laying it off or spinning his marker and going for goal. It allows for more variation in our play.
You can only lay it off if you have support - our strikers have no support so Benteke would be no better than what we have.
You can only spin your marker and head towards goal if you are left with just one (or sometimes two) marker(s). Teams don't play against us the way they do Villa - Benteke would receive the ball for us, turn his man and find the other 9 outfield players and the keeper still in his way. If he can get past all of them and score on a regular basis, I'll buy him for the club myself.
