Thibaut Courtois got 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 three 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.
Radamel Falcao announced his return to goalscoring action as Monaco's 1-0 win prevented Arsenal from winning the Emirates Cup.
Hopes were high that the Gunners would lift the trophy for the first time in four years, but Arsene Wenger's side were caught napping when Falcao ghosted into the box and nodded home from a free-kick eight minutes before the interval.
Instead, it was Valencia who took the trophy after earlier beating Benfica 3-1.
An eventful day at Goodison Park saw Everton celebrate Leon Osman's 11 years of service and present record-signing Romelu Lukaku to the crowd, but they still could only manage a 1-1 draw with FC Porto.
The Toffees struggled to craft and take clear-cut opportunities in the absence of a recognised No. 9, but Steven Naismith still managed to coolly sidefoot them in front just before the interval.
It was then that Lukaku was paraded to rapturous applause and his potency up front was clearly the missing ingredient as Porto fought their way back into the game and Jackson Martinez grabbed a deserved equaliser.
