A strange twist of events saw James Corden take over as Arsenal manager for the day.
In the video above, The Late Late Show host assumes Arsene Wenger's role and begins to put the players through their paces.
Starting with a slap on the bum, Corden soon has Wilshere, Walcott and co singing Wheels on the Bus as they travel to the training ground.
A warm up is next on the cards and the Gavin and Stacey star gets the Gunners to "open their gates" and "grab the pineapple".
With the players wondering where the session can go from here, Corden gets the lads working on their celebrations.
Bellerin's tap in is followed by his teammates mocking up a frying pan which cooks the Spaniard. Don't ask.
Following the session, a few of the players were asked for their thoughts.
Wilshere said: "He's terrible. He's the worst coach I've ever worked with. His breath smells, and when he's talking he spits on us."
Bellerin said: "I think he should stick to singing in the car. I will never get this hour of my life back."
Brutal.
