(EPA Images pic)MUNICH: Arsenal coach Mikel Arteta said the club was "concerned" about the severity of an injury to winger Bukayo Saka after Wednesday's pulsating 2-2 Champions League draw at Bayern Munich.

Saka, Arsenal's joint top goalscorer this season alongside Victor Gyokeres, went off early after falling to the turf grabbing his thigh and was replaced by Eberechi Eze.

Eze scored Arsenal's opener and Declan Rice scored late to clinch a draw for last season's runners up after an Alphonso Davies goal and a Harry Kane penalty for the hosts.

Arteta said Saka's injury was as yet unclear, but told reporters the club's medical staff were worried.
