Arsenal captain Martin Odegaard and forward Bukayo Saka will be assessed before their Champions League quarter-final second leg with Bayern Munich, manager Mikel Arteta says.
Odegaard was taken off with 10 minutes remaining in Arsenal's defeat by Aston Villa on Sunday, while Saka was seen limping towards the end of the match.
"We will assess them tomorrow and see how they are," said Arteta.
Arsenal and Bayern Munich drew the first leg 2-2 in London last Tuesday.
The Gunners are hoping to reach the semi-finals of the Champions League for the first time in 15 years.
