Arsene Wenger has confirmed Nacho Montreal could miss at least Arsenal's next four games.
The Spaniard suffered a bank injury during the Carabao Cup final loss to Manchester City on Sunday.
And speaking before the Gunners host City in the Premier League on Thursday night, Wenger said Monreal was facing an extended stint on the sidelines.
"Monreal is out for the two games - Thursday and Sunday," said Wenger.
"He might be out for two more - Milan and maybe one more.
"The rest, everybody is fit."
