Arsenal fear Aaron Ramsey could be missing for eight weeks.
The Telegraph says Arsenal expect they will be without top scorer Ramsey for at least the next four weeks.
Ramsey was waiting on Friday night for the results of a scan on the thigh injury he sustained in the 3-1 Boxing Day win against West Ham United.
Should the scan reveal a tear, then Ramsey could be out for six to eight weeks but Arsenal are hoping for confirmation that the injury is just a strain.
