8. Serge Gnabry (Arsenal)
Serge Gnabry is very highly thought of at Arsenal, and really caught the eye this season with his stand-out displays in the NextGen Series. The 17-year-old winger also came close to the first team on several occasions, with brief but impressive substitute appearances in the Premier League, Champions League and League Cup. Signed from Stuttgart at the start of the season, he looks like being another big talent coming out of German football at the moment. With Arsene Wenger’s fondness for young players, we could be seeing more of Gnabry next year.
