Arsenal fear Bukayo Saka could be unavailable for up to eight weeks after the forward suffered a quadriceps injury against Bayern Munich.
The injury could keep Saka out of action for around two months, although the supplied information does not confirm a precise recovery timetable.
Saka’s potential absence would leave Arsenal without one of their forwards for a significant period. The latest known situation is that the club is assessing the injury and fears he could face a lengthy spell on the sidelines.
