Arsenal boss Arsene Wenger says Joel Campbell or Alex Iwobi could take over from senior players on the right-hand side of the pitch.
With Aaron Ramsey, Alex Oxlade-Chamberlain and Theo Walcott all out injured, the Frenchman has a difficult decision to make ahead of today's away game against Swansea City.
And he admits that it will be a challenge to pick the right players to face Garry Monk's men.
"[Joel] Campbell and Alex Iwobi," Wenger said.
"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.
"My short-term option is [to play] Campbell or Alex Iwobi 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.
"Santi [Cazorla] can play there as well but he has become very important centrally.
"The problem sometimes is that you can destroy two departments if you move one player out. We control the ball better with Santi in the middle.
"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."
