Mikel Arteta gave an update on Martin Odegaard's injury after the Real Madrid loanee was forced to miss Arsenal's 1-1 Europa League draw with Slavia Prague on Thursday.
Odegaard returned to Emirates Stadium from international duty with Norway last week nursing an ankle issue, but still managed to play the full 90 minutes of the Gunners' 3-0 Premier League defeat to Liverpool last weekend.
Arteta decided not to risk the 22-year-old again in the first Europa quarter-final leg, however, and admitted post-match that the playmaker may need some extra time on the sidelines to make a full recovery.
