Football fans on social media spotted something different about Manchester City's FA Cup final kit.
Pep Guardiola's side are currently on course to become the first men's side in English football to claim a domestic treble, as they lead Watford by six goals to nil at Wembley.
But eagle-eyed observers have spotted that Guardiola's men are wearing a different shirt for the clash.
While to most fans it will look as though City are in their normal home strip, there is change in the wording from their sponsor on the front.
Normally, City's shirts have "Etihad Airways" across the front, but for today's game that was changed to "Choose Etihad" instead.
City had already been given been given permission to omit the he FA Cup affiliation patch on their sleeve, reportedly due to the fact it advertises competition sponsors Emirates, rivals of the club's main sponsors Etihad Airlines.
And it appears the club have taken a sly dig at the competition's headline sponsors.
