For your third question
I'm from Turkey and i have spent two brilliant years with this guy.He was my classmate 6 years ago. His father(Mesut Unal) is also a former player for Bursaspor. I can say that his father really cares about his son's football life. When he arrives England I'm sure that his parents will come with him. He doesn't like night lifes. He's trying to improve his finishing skills and I know that he is very talented about that.
For his weakness, he is 185 cm I guess, but he is not strong enough to fight with other defenders . Also he doesn't create chances like Aguero. If someone( Silva or nasri) creates chances with right passes to him , I know that he finishes them with scoring goals .
Last of all take care of this guy in England cause we know that he is the great future for Turkish football and European football also.
Do you know what his English is like?
