It doesn't surprise me that he looked lost. His game requires like minded players feeding him the ball & making the runs to recieve the pass from him. A lot of our kids have lost their way due to the same thing. We teach them to play one way then send them into an alien environment. Some can adapt, some are ruined.
David Silva would struggle in a lower league shit football team imo. Wheras Sterling wouldn't.
I recon Byrne would have been very close to our frst team level when he came back from Holland. No idea what he'll be like now, but if we can revitalise him, we have a viable first team squad player imo.
