Jack Wilshere insists Arsenal will recover after being defeated by Borussia Dortmund in a disappointing start to their Champions League group campaign.Ciro Immobile and Pierre-Emerick Aubameyang struck in a 2-0 victory for the Bundesliga club, but the winning margin could have been greater at Signal Iduna Park on Tuesday night.
In what was seen as Arsenal's toughest fixture in Group D, the performance has raised concerns over their ability to make any meaningful impact in Europe this season.
Adding to the defeat is the ankle injury that forced Wilshere off in the closing stages.
Arsene Wenger played down the severity of the sprain, but a more informed assessment is expected ahead of Saturday's Barclays Premier League trip to Aston Villa.
"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," Wilshere told the London Evening Standard.
"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.
"It was disappointing against Dortmund. They are a good team and we have got to be a bit smarter when we come to places like this, with their gameplan - they wanted to press us high up the pitch and we let them do it in the first half.
"We started the second half quite brightly in the first couple of minutes and then unfortunately it was the same thing again on the counter attack and then the game is over.
"We knew what they were going to do. We should have played maybe a little bit longer in the first half than trying to play our football in our half of the pitch because once you lose it there, they are straight onto us.
"We had a few chances and even at 2-0, Danny had a chance and if he had scored that maybe the last 10 minutes would have been a different game."
Wenger will hope to have full-backs Nacho Monreal and Calum Chambers available for Villa after they missed out against Dortmund through injury and illness.
