I'd rather see chances missed than not having them at all like, for example, is in lloriente's case
CFs don't create chances, they convert them. Cavani wouldn't get the ball and dribble past 4 defenders like Messi or R9 did, neither will Llorente. Both are viable solutions in the air, Llorente is actually better, but is way slower and has perhaps worse technique. That has nothing to do with creating chances.
