Arsenal manager Arsene Wenger has confirmed that defender Hector Bellerin will not feature against Tottenham Hotspur this weekend.
The youngster was absent in Arsenal's 5-1 thrashing by Bayern Munich in mid-week and is again ruled out with Mathieu Debuchy expected to keep his place in the starting line-up.
Defender Laurent Koscielny will have a late fitness test on Sunday ahead of the North London derby.
"From the unfortunate Wednesday night, we have no injuries," Wenger revealed.
"Players back for Sunday, we might have [Laurent] Koscielny and I think that it is. [His chances are] eighty per cent. He will have a test tomorrow.
"[Mikel] Arteta has a test tomorrow morning. [Hector] Bellerin is a doubt already.
"Mathieu [Debuchy] needed a little competition. Game after game he has basic fitness and now with another game he should be better. Bellerin unfortunately will not be ready, I think he could be back after the break."
