He has nearly as many yellow cards as league goals, so agree to disagree on his attitude.
Also, I'm not sure why you're comparing him to two strikers who took their chances; he'll NEVER reach their level. For those who don't follow African football, I'll point out that he isn't even considered good enough for a starting berth for the Senegalese NT.
Finally, do not put words into my mouth. I never said, "He isn't good enough for us." If he wants to have a successful career at the highest level, he needs to switch to wing forward. The lack of a killer instinct is obvious, and it cannot be taught; it is either present or not.
