Kenneth Omeruo is a player who the casual Chelsea fan may not know too much about, given the fact he is yet to even feature on the bench for the club.
The Nigerian is just 19 and has enjoyed a 'breakout' year on loan at ADO Den Haag in the Eredivisie, and is expected to rejoin Chelsea for pre-season.
His successful year saw him become an African Nation Cup champion, also featuring at the Confederations Cup in Brazil.
Tonight he was braced for the biggest challenge of his career, going head-to-head with an irrepressible Spain side.
Omeruo was playing in central defence, up against Roberto Soldado who was preferred to Fernando Torres in the Spain attack.
Unfortunately if Jose Mourinho was observing to see how he coped against a strong Spain side, he won't have deduced much from the match.
Omeruo went down injured after colliding with Cesc Fabregas, hurting his shoulder in the challenge.
He was substituted just 11 minutes in, with Spain 1-0 up after a third minute Jordi Alba goal.
Omeruo is the second Chelsea defender to suffer injury in the tournament, with Brazil's David Luiz suffering a broken nose.
The extent of Nigeria defender Omeruo's injury is yet unknown, but Chelsea fans will no doubt be crossing their fingers it is not too serious and that it won't affect his attempts to impress in pre-season.
Do you think Omeruo can play a role at Chelsea next year?
