Lots of people still asking why Kalvin's so different from his Leeds days, forgetting that massive shoulder injury that occurred in between. Shoulder/back injuries finish off all sorts of players. Remember what it did to Negredo? One of the most powerful and deadly strikers in the league reduced to almost nothing. Had to leave the UK to get his career back on track and when he came back just two years later he was part of a team that went down with a whimper. And Kalvin wasn't as good as Negredo was. His level's the Championship now and I'm staggered teams like West Ham and Everton are even considering him.
