He seems very calm in the interview and humble (and like some said earlier, he is quite articulate, Kompany-esque). I'm still sceptical (not see enough of him) of the signing, but he is one for the future and seeing as he was a free agent, if in the future he is sold, it will be an instant profit. So it's all good.
Maybe in a couple of years Donyoh will be the new Guidetti on this forum, haha :-)
