Arsenal boss Arsene Wenger has not rued his decision to play an inexperienced side against Porto in the Champions League.
Knowing they will now play a group winner in the next stage, Wenger believes the Gunners can bounce back and are a threat to any potential opponents.
"It will be difficult but we will be up for it and have a chance against anyone in Europe," said the Frenchman.
"We were quite comfortable in the first half until the goal tonight. What was disappointing was that when we tried to come back we were not capable of being dangerous, we lost balls and then we were on the verge of conceding more."
