Goalkeeper: Thibaut Courtois | Chelsea (on loan at Atletico Madrid)

Manchester United's David de Gea was just too old to qualify for this Under-21 XI, so Thibaut Courtois takes the No. 1 jersey, even though he has yet to play a single minute of Premier League football.

No Premier League goalkeeper playing regularly is younger than De Gea, but Courtois - who could be Chelsea's No. 1 from the start of next season - is.

The Belgium international is already one of Europe's best goalkeepers. Can Chelsea hold onto him?
