Hector Bellerin returned to full Arsenal training on Friday and is understood to be making good progress in his recovery from concussion.

Bellerin, who suffered the injury after receiving an elbow to the head from Marcos Alonso in last week's 3-1 defeat at Chelsea, received the all-clear from an MRI scan earlier in the week but is still on the six-step graduated return to play protocol.

Football Association guidelines for head injuries mandate that a player who receives "enhanced care", as Bellerin did when he was immediately substituted at Stamford Bridge, must wait six days before returning to action.
