Arsenal will be without four key players when they travel to Ludogorets in the Champions League on Tuesday.
Santi Cazorla, Theo Walcott, Hector Bellerin and Nacho Monreal will all remain in England as Arsenal visit the Bulgarian outfit aiming to stay top of Group A.
Carl Jenkinson will deputise at right-back after Bellerin picked up a slight knock in training, while Kieran Gibbs will continue at left-back.
Walcott trained with the squad on Monday but has been deemed unable to take part, while Cazorla continues to nurse an Achilles injury.
The Gunners beat Ludogorets 6-0 earlier this month but Arsene Wenger expects a tough test.
“The result was flattering for us because we scored many goals,” he said.
“But I don’t forget that we were facing a good attacking Ludogorets team in that first half.
“When the game was very tight, we needed a strong defensive performance to stop them being dangerous because they had many chances as well. We will have to again.”
