I think the journey from Russia may be too much for you to attend, Master. The youth team is good. Chuba's skills are jokes, man. Bellerin is like a Spanish Cafu. And Sead Hajrovic is the best defender at youth level, already in Bosnia and Herzogivina squad at senior level. The next Tony Adams.
The U21 team got to the semi-final of the Next-Gen series which puts them top 4 in Europe. I am not sure that results are really a perfect indication of ability, or success at this level though. The step up to the first team is massive, I think, and you are just looking at one or two players that can make the step up at any one point. If they are hidden in 9 or 10 underperformers, and lose a game or six, then it really doesn't matter. The measure of success is getting those one or two kids to the next level, not winning games.
Ah sorry, so many of the players overlap, I just kind of lump them into the general "Youth" category.
