Arsenal remain unsure when Santi Cazorla will be fit to return to action after confirming that he sustained knee ligament damage at Norwich.
The Spanish midfielder jarred his knee during a 46th-minute clash with Norwich midfielder Gary O’Neil, but still played the entire 9o minutes of the 1-1 draw.
“The worrying thing was that it got worse,” said Arsene Wenger after the match, leading to questions over why the Gunners boss did not withdraw the player during the match.
Cazorla has already been ruled out of Saturday’s Premier League game at home to Sunderland and next Wednesday’s decisive Champions League tie at Olympiakos, which the Gunners must win by any other scoreline than 1-0 or 2-1.
The Gunners are currently missing 10 players through injury, with Alexis Sanchez (hamstring) now ruled out for three-four weeks.
With central midfielder Francis Coquelin ruled out until February, Wenger is likely to turn to a midfield pairing of Mathieu Flamini and Aaron Ramsey to take the Gunners through the festive period.
