It's hard to gauge which will be given a chance as all have undoubted quality but may not get first team action yet, but these are my 3:
Callum Hudson-Odoi (Chelsea) is lethal - hopefully Sarri will give him a chance.
Vinicius Junior (Real Madrid)
Ryan Sessegnon (Fulham)
Other worthy mentions: Phil Foden (Man City), Leon Bailey (Bayer Leverkeusen, hopefully move to Chelsea ;-)- )
Which 3 youngsters do you guys think will do great this season. Ideally, it is better than the names aren't really heard of. No older than 20 also.
Mine are
mboula (Monaco)
Guendouzi (Arsenal)
Torres ( Valencia)
I haven't seen that much from Torres though, same could be said for Guendouzi, but they look like hot prospects.
