Arsenal's Alexis Sanchez says fear of injury is hitting his form

Arsenal forward Alexis Sanchez has revealed a fear of suffering another injury has resulted in a dip in form.

The Chile international scored 10 goals in six games for club and country between September and October.

But the 27-year-old suffered a hamstring injury in the 1-1 draw against Norwich at Carrow Road in November and has hit just three goals since returning to action in January
