Mesut Ozil does not appear to have travelled to Manchester with the rest of the Arsenal squad, for Monday night’s meeting with United at Old Trafford, Manchester Evening News reports.
Photographers did not spot Ozil getting off the coach at the team’s hotel.
There were 18 Arsenal players, who made their way into the hotel.
Hector Bellerin and Kieran Tierney, two players who also made their first appearances of the season against Nottingham Forest, were not sighted either.
Alexandre Lacazette hasn’t featured since September 1 due to an ankle problem and is not expected to return until after the October international break.
