The 17-year-old made the huge move from Birmingham to Dortmund in the summer, but has hit the ground running in the Bundesliga and has already played far more minutes than was expected of him.
Speaking about the striker's maturity belying his years, the Young Lions boss said: "He is the oldest young player I have ever come across. He has settled down now, he is comfortable in his environment, he is giving stick out to the lads and he is getting a bit back.
"He has to do his education... he is learning German, he is trying to learn how to drive and he is doing his driving test in Germany. He has a lot going on and he is loving the fact that he can just go out and train and be free.
"He has made a brilliant start at Dortmund to get the young player of the month. I fully expect him to build on that and I have been really impressed with him as a person and as a player. He is really a credit to his parents, a cracking guy, he comes into the room with a massive smile."
