Arsenal defender Takehiro Tomiyasu was not pictured in an open training session on Tuesday morning.
The Japanese international’s absence has prompted speculation about his fitness ahead of the game against Manchester United.
Some have suggested that Tomiyasu simply had the day off but it remains to be seen whether he will be in the travelling party for the clash at Old Trafford this weekend.
The fullback played the full 90 minutes during the 3-0 win over Bournemouth on Saturday and there was no indication after the match that he had picked up a knock.
