Gunners missing key duo
Sokratis Papastathopoulos and Laurent Koscielny are both set to miss out when Arsenal take on Cardiff City tonight.
Sokratis and fellow centre-back Koscielny were injured in last Friday's 3-1 home defeat to Manchester United in the FA Cup, with the game expected to come too soon for the French defender - whose bruised jaw is being monitored daily.
Sokratis is expected to be out for "maybe two or three weeks," boss Unai Emery said, while Koscielny's jaw is bruised, but not broken.
The Frenchman could be back for Sunday's trip to holders Manchester City.
Right-back Hector Bellerin, centre-back Rob Holding (both knee) and Danny Welbeck (ankle) are long-term absentees, while Henrikh Mkhitaryan (ankle) is back in training.
Arsenal beat Chelsea 2-0 in their most recent Premier League match, a result which will count for little if the Gunners fail to beat the relegation-threatened Cardiff.
"If you win against Chelsea and you don't win tomorrow, you are losing three very important points," Emery said. "Tomorrow we need to impose and to adapt. I think they're going to play with a big motivation, also and finding a lot of duels against us.
"We need tomorrow to be concentrated for the three points like we were against Chelsea."
