I'm not saying he's not good enough, I'm just saying that it's not in the top league, so some players look like world beaters, plus we all know how YouTube makes people look, Ghilas is one & I'm sure there's plenty of others. Proschwitz was from the German second division & he struggled in the Championship. True there is no guarantee of any player being a success or a failure just because of the league they come from, I was just pointing it out.
Having just seen the video he does look a lot like Cameron stewart. A lot. Fast, full of tricks, tries to do too much alone, not much end product. He looks tougher and more physical though, less scared to run at people and has some tidy finishes in that collection. He could develop into a very tidy player in time, but he's not first team material. I'd take him though, young with potential and could make a great impact sub with his attributes.
If he's only 20 he won't have been named in the squad as select player. The European squads are like the PL ones, 25 players over 21 and as many as you have on the U21s list.
Auxerre were actually an L1 side in 2010 until relegation in 2012. He made the subs bench in L1, but nothing else. ****it you're right. He could be a world beater or he could be Ghilas.
