The loss of the Japan international will come as a blow for Arteta as he has been in fine form for the north London team this season. Meanwhile, they are already without the likes of Jurrien Timber, Emile Smith Rowe, Thomas Partey and Fabio Vieira due to injury.

WHAT NEXT FOR ARSENAL?
Despite the absence of Tomiyasu, Arsenal will be hoping to maintain their six-game winning run in all competitions when they visit Aston Villa in the Premier League on Saturday. Three days later, they will travel to Eindhoven to face PSV in their last Champions League group stage game. The Japan international's injury will likely see Ben White return to the starting line-up.
