Thibaut Courtois received the nod ahead of Petr Cech for Chelsea's game with Werder Bremen, but he was unfortunate to find himself on the wrong end of a 3-0 scoreline.
The Belgian keeper, returning to Stamford Bridge after two years on loan in Spain with Atletico Madrid, was beaten from the spot by Eljero Elia before Ludovic Obraniak's powerful header made it 2-0 at half time.
Didier Drogba made his return to action for Chelsea in the second half, but Felix Kroos made it 3-0 with another spot-kick late on.
