The Gunners head into the clash against their local rivals at Emirates Stadium looking to make it back-to-back Premier League wins for the first time this season after their 3-0 triumph at Aston Villa last weekend.
Midfielder Abou Diaby was involved in Friday’s training session at London Colney after the Frenchman made his first start in 18 months in the 2-1 League Cup loss to Southampton in midweek.
Arsene Wenger also has Mathieu Flamini available for selection again after he recovered from a dead leg, with Kieran Gibbs and Per Mertesacker also both available.
However, Nacho Monreal remains sidelined with a back problem, with Olivier Giroud, Theo Walcott and Mathieu Debuchy among the long-term absentees.
Arsenal won the same fixture last season 1-0 thanks to Giroud’s goal at Emirates Stadium.
Here are some of the best pictures from Friday morning’s training session at a grey and gloomy London Colney.
