Dude, we know he has something. That's not even a question. His time at Leipzig put an end to that discussion, and our new DoF wanted to sign him for his previous club. I think you'll see him be a prominent player for the club this season, and if he's not, then I'd suggest that is a failure of management. The ability is oozing out of him, and it seems like the most progressive, forward thinking scouts/DoFs around Europe are all well aware of that, and would love to get him.
Brands' quote (and one of the first things he's said about any of our player's specifically, which tells you a lot):
Listen, I hope he does make it, he's shown flashes for us in the past. But we still don't know how he'll fare in an important role for us in the Prem. He did well in Leipzig after a slow start, and I hope he can continue that form for us. But if he's struggling and done nothing for us in 6 months, then we would be daft not to explore other options.
So I am all for giving him a chance and a proper run in the first team to show what he can do. But if there are minimal results from that run, then do you persevere or do you look to improve by looking to buy someone else more proven?
