Arsenal fear Hector Bellerin may not be available for the start of next season due to a knee injury.

The Spanish right-back was forced off with an injury in the Gunners' 2-0 victory over London rivals Chelsea at the Emirates on Saturday.

The Mirror says Bellerin is out for the rest of the season - and could even miss the beginning of NEXT campaign - after rupturing his cruciate knee ligament.

Bellerin only recently returned to first team action for Arsenal in their defeat by West Ham last week, following a month-long lay off with a calf complaint.

The speedy defender looked to be getting back into the swing of things, and even created the Gunners' opening goal against Maurizio Sarri's Blues, before coming off the pitch on a stretcher after collapsing in pain.
