Little surprise, then, to see the players allowed some time off to enjoy themselves at Christmas with the squad taking to fancy dress for their festive bash and Lukas Podolski posting the results on Instagram.
The Germany international came as the Incredible Hulk and posed alongside Mesut Ozil, who opted for a Superman costume, Santi Cazorla, who came as Super Mario, and Mikel Arteta, who chose Zorro.
Podolski, who wrote on Instagram: "Just on the way to our team dinner!", certainly looks fully recovered from a hamstring injury that has seen him sidelined in recent weeks.
The German striker also posed alongside a pair of Bananas in Pyjamas and, in case you haven't guessed, yes; that is Theo Walcott on the left and Kieran Gibbs on the right.
