Chelsea's Belgian goalkeeper, was twice nutmegged by Lionel Messi as Barca booked their place in the Champions League quarter-finals at the Blues' expense with a 4-1 aggregate victory over Antonio Conte's side.
Both of Messi's goals were finished through Courtois' legs, while he also failed to cover himself in glory with a weak attempt to save Ousmane Dembele's goal - Barca's second of the night.
Considered one of the best goalkeepers in the Premier League - perhaps second only to Manchester United's David de Gea - such a poor performance seems out of character for Courtois.
