Francis Coquelin could be set for a lengthy spell on the sidelines due to a knee injury sustained at the weekend, according to a report.

The Sun claim that the Arsenal midfielder may be ruled out of action for months as the club await the results of a scan on his knee.

The report details the club’s medical staff are concerned the 25-year-old has suffered more damage to his medial ligaments, which saw the Frenchman miss two months last season.

Coquelin is set to find out on Monday the extent of the damage but there are fears he may not play again in 2016.

The combative midfielder was replaced in the 3-0 win against Chelsea on Saturday and replaced by team-mate Granit Xhaka.

He has been a crucial player at the beginning of the season and manager Arsene Wenger has selected him despite having a wealth of midfield options.

Coquelin has started five of the club’s six league games this season as well as the Champions League draw with Paris Saint-Germain.

Arsenal are blessed with several skilful players but Coquelin provides some determination in the middle of the park.

He has made 114 senior appearances for the Gunners since his promotion from the academy and is still searching for his first goal.

Coquelin was sent on loan to Lorient, Freiburg and Charlton during his development and he has now become an important member of Arsenal’s first-team.
