New Arsenal signing Danny Welbeck was mocked by teammate Alex Oxlade-Chamberlain as the squad prepared for their official team photo.
Oxlade-Chamberlain, who plays alongside Welbeck at international level for England, poked fun at the striker's nickname 'Dat Guy' before joining the rest of the squad.
Welbeck joined the Gunners on transfer deadline day last Monday from Manchester United for a reported £16m fee.
The club have released behind-the-scenes footage of the team and manager Arsene Wenger as they posed in their new Puma Arsenal kits.
