The Ivory Coast international has already made a big impression on his new colleagues, in more ways than one.
Swansea defender Garry Monk said: "He is a unit, isn't he? The first day in training and going up against him in set-pieces I got injured at his expense; I pushed off him and dislocated my finger. It says it all just how big a boy he is.
"It's not just his size. We were in training the other day, myself Leon [Britton] and Ashley [Williams] were asking him to take a shot. He nearly broke the net.
"He's probably the hardest striker of a ball I've ever seen in football. I don't think I've seen anyone hit a ball like it."
