Perhaps the team had been focusing too much on their fancy dress outfits prior to their 2-1 defeat at the hands of Chelsea earlier in the day.
England international Gareth Barry made a convincing 'Where's Wally' in a striped red top and matching hat, although he did get the costume slightly wrong.
What I want to know is...
...Where's Balotelli?
If Balotelli had attended this party, he didn't need to wear something extra.
He's got a crazy face and haircut of his own.
