Mikel Arteta thinks Arsenal deserved more from their Champions League clash with Borussia Dortmund.

Arsène Wenger's side fell behind to Henrikh Mkhitaryan's first-half strike but restored parity before the break through Olivier Giroud and then took control in the second half. However Arsenal were beaten by Robert Lewandowski's breakaway goal eight minutes from time.

We knew it was probably the toughest group in the Champions League. We don't think any differently now

"I think we deserved better," said Arteta. "We did the hardest bit, to score the goal just before half-time. It was when we had control of the game and created the best chances when we just got caught on the counter-attack. That was disappointing.

"I don't think we chased the game too much, we just gave the ball away at the edge of the box. We know that they are a very good side on the counter-attack and I think we had kept them really quiet, but we conceded the chance and they scored.

"It's going to be tough [to qualify], we knew it was probably the toughest group in the Champions League. We don't think any differently now.

"We're still capable of going through but we're really disappointed with the way we lost the game."
