The Togolese striker, who recently committed his future to the Gunners, converted the spot kick in the 49th minute after Michel Salgado brought down Robin van Persie.

Arsenal had the better chances throughout the game and came close to breaking the deadlock on several occasions.

Adebayor in particular was a constant threat to Real's Polish keeper Jerzy Dudek.

Spanish champions Real suffered a blow when Dutch winger Wesley Sneijder sustained what looked like a serious injury.

He was carried off the pitch on a stretcher, making way for Javier Saviola.

"It's a very difficult moment for him - he's in a lot of pain. He should have another test but we haven't had a good look yet," Real coach Bernd Schuster said.
