The loss of Coquelin with a knee injury adds to Arsenal's seemingly perennial injury woes with the likes of Danny Welbeck and Tomas Rosicky enduring lengthy absences.
But Wenger says the problem is no worse than previous seasons, with Aaron Ramsey, Alex Oxlade-Chamberlain and Theo Walcott due to return soon.
"We've been hit very hard in November because until the Sheffield Wednesday game in the League Cup we had a good record but since we have lost a few players," he said.
"We have Ramsey and maybe Oxlade-Chamberlain back for the weekend and Walcott will be the next one - all the other players are long-term injuries."
