Gunners boss Arsene Wenger is ready to shuffle his pack and Coquelin could come back into the side having recovered from the knee injury he suffered in the win over Chelsea last month.
It was originally feared the midfielder could be missing for three months but he made his return as a substitute against Swansea.
"I feel 100 per cent fit. It took me a few weeks to get back to full fitness, but now I feel good," said Coquelin. "When you make these kinds of tackles, and this happened before against West Brom, you are a bit scared. It was a similar tackle to then.
"The good thing was that I could run back onto the pitch afterwards, even if I couldn't stay on for long. The scan which followed was all positive so that was great news."
Couqelin's place in Arsenal's side has arguably never been under more pressure following the recent additions of Granit Xhaka and Mohamed Elneny.
But the Frenchman will be ready whenever he is called upon.
"Let's not forget we are Arsenal Football Club," he added. "There's always going to be great quality in this squad. You have to be ready for a fight. It's good for me to improve my game and give even more in training and every game. It can only improve the whole squad."
