Arsenal host Shakhtar Donetsk in their third Champions League game of the season and could be without several key players.
Bukayo Saka, Jurrien Timber, Martin Odegaard and Takehiro Tomiyasu were not present in training on Monday afternoon.
Manager Mikel Arteta claimed in his press conference earlier today that both Saka and Timber will be assessed during training this afternoon.
However, neither player has been involved and will probably miss the game tomorrow.
Arsenal have taken four points from their opening two games in the Champions League, and they will be keen to secure all three points against the Ukrainians on Tuesday.
Being without Saka will be a huge blow, but they have Raheem Sterling as an option to play in the position.
William Saliba will also be available for selection despite getting sent off in the Premier League game against Bournemouth on Saturday.
However, the France international will be unavailable to play for Arsenal against Liverpool on Sunday unless the club appeal his red card.
Shakhtar drew 0-0 against Bologna in their opening game of the competition before losing 3-0 at home to Atalanta in their last game,
The Gunners will fancy the chances of defeatingt them even without some of their key players.
Arteta will hope both Saka and Timber will be available for selection against Liverpool, as facing the Premier League leaders may be their toughest game of the campaign to date.
