Arsene Wenger has revealed Hector Bellerin will be out of action for four weeks after picking up an injury in the north London derby with Tottenham.
“Hector is out for four weeks,” Wenger told reporters at his press conference on Thursday. “He got injured in the last 10 seconds against Tottenham in a very strong tackle from Danny Rose.”
The Spanish right back will miss at least eight games for the Gunners, including the match against Manchester United this Saturday.
He will also have to sit out the crucial Champions League ties with Paris Saint-Germain and FC Basel, and the EFL Cup quarter final with Southampton.
The Gunners will also have to do without him for Premier League clashes with Bournemouth, West Ham, Stoke City and Everton.
He could also be doubtful for the match away at Manchester City on December 18.
It means Wenger has something of a selection problem at right back, given that Mathieu Debuchy is struggling with a calf problem, and Carl Jenkinson is still not at full fitness.
Former Bolton defender Rob Holding could be an option.
