I don't see anything special about Tosun but then again nor should we expect to yet. He hasn't played a full game of football for over two months, he's been called out by his manager in that time, he's in a different country, different language, different team-mates and into a club which is all over the place.
We'll get a better view if he plays every week from here on in but more likely after a full pre season we'll get a better idea of what he can offer in August. Still, if he continues to hit the back of the net most weeks it won't do his confidence any harm whatsoever.
