The duo were in action with the rest of the Gunners squad as they were put through their paces at a wet and gloomy London Colney on Saturday afternoon.
Walcott could be in line to make his first start of the season for Arsenal following his lengthy spell out injured following knee surgery.
Also pictured were the likes of Santi Cazorla and Lukas Podolski, as well as Calum Chambers and Alex Oxlade-Chamberlain.
