Chelsea defensive midfielder Mikel Obi has apologized for his costly blunder which led to Juventus leaving Stamford Bridge on Wednesday with a draw.

With 10 minutes left, Juventus were trailing the European champions 1 - 2. Then a mistake by the Super Eagle led to the equalizer by the Italian champions scored by Fabio Quagliarella.

Mikel told skysports: ''If I want to make up an excuse, I can. But, for me, I gave the ball away. I put my hands up, we move on.

"I'm sorry about the mistake, but there are no excuses."

Chelsea are away to Danish club FC Nordsjælland in the next round of Europe's elite competition in two weeks time.
