On Normann, I watched him a fair bit playing for our u23s and he stood out: great technique and vision. He wasn't given any opportunities to break through, because our then manager wasn't exactly keen on blooding young players. I'm not surprised he sought pastures new.
Interesting, so did I and thought the opposite, clearly had vision but looked slow and was caught in possession which cost us a goal on one occasion. Certainly was not better than Propper, Stephens or the young Bissouma at the time, and IMO CH got it spot on, as he did with Alzate’s development (in terms of the Swindon loan).
