Arsenal midfielder Jack Wilshere has tipped his side to come back stronger after they were outplayed in a 2-0 loss to Borussia Dortmund in their opening Champions League game.

Goals from Ciro Immobile and Pierre-Emerick Aubameyang gave Dortmund a winning start at Signal Iduna Park on Tuesday and the German club's dominance was such that the margin of victory could have been even greater.

It was a chastening entrance into the competition for Arsene Wenger's side, who have drawn their last three Premier League games, but Wilshere says there is plenty of time to turn the situation around in Group D.

"We'll bounce back. Our next Champions League game (against Galatasaray on October 1) is at home and hopefully we'll get the three points," the England midfielder told Wednesday's London Evening Standard newspaper.

"It's never nice to lose a game. We wanted to come here and win. But that was our first Champions League group game.

"We have got five more, so we have an opportunity to try and get 15 points and that is what we'll try to do.

"It hasn't quite clicked for us yet, but we've got a lot of quality players and I'm sure it'll come right."

Wilshere had to leave the field to receive treatment after spraining his ankle in the latter stages of the game, but Wenger played down the severity of the injury.
