Arsenal midfielder Mesut Ozil has declared that he needs no extra motivation to perform against Borussia Dortmund tomorrow night, insisting that the Gunners deserved more from their Champions League clash two weeks ago.

Dortmund left the Emirates with all three points thanks to a 2-1 success secured by Robert Lewandowski, a defeat Ozil has admitted was tough to take.

Ozil started his senior career with Dortmund's arch rivals Schalke 04 but does not see that as a factor ahead of tomorrow's return to the Ruhr, while revealing that he already feels very comfortable with life in London.

He told Bild: "There is no sting, but every defeat annoys me. Home defeats especially. And in the Champions League more than ever. We were about to turn the game around. But Dortmund have made ​​the second goal.

"I've been here for more than six years away from Schalke. It does not matter anymore, Champions League games are motivation enough.

"Honestly, Arsenal makes everything fun. The coach, the players, living in London, I feel really comfortable there."

The 25-year-old has made 11 appearances for Arsenal since his club-record £42.4m switch to the Emirates from Real Madrid, scoring three goals.
