Arsenal boss Mikel Arteta admits Jurrien Timber could play again this season.
The Holland defender is recovering from an ACL injury suffered on the opening day.
Arteta said: "I really hope so.
"He's doing really well and he's going to start doing some bits with us in the next week and then we have to see. Hopefully the answer is yes.
"We have missed some big players and we still are, but we have to adapt to that. We know the impact they'll have when we have a fuller squad."
