Arsene Wenger has challenged his squad to show its depth and quality as he looks for solutions on the right flank.
Wenger is confident his side will adapt in south Wales, and says the likes of Joel Campbell could have an important part to play.
“It is always disappointing to lose players but we are equipped first of all with the quality of our squad and we are equipped mentally as well to deal with anything,” the manager said.
“My short-term option is [to play] Campbell or get one more defensive midfielder in like Flamini and put Cazorla on the flank. I haven’t decided yet. We will find solutions and I have to find the right one.
“I have been very impressed with Campbell, his attitude is outstanding and his daily dedication in training and his desire to improve is absolutely outstanding.
“I think he can be a big help for us, and he can play centre forward don’t forget that. In the coming two to three months he can be a very important player for us.
“This is a challenge for me and for the players who come in to show their quality. At the end you can find yourself with a bigger squad - that is what happened with Coquelin and Bellerin last season.”
