Manchester City are seeking a historic domestic treble in the FA Cup final against Watford at Wembley.
A David Silva strike gave City a 1-0 lead before they doubled their advantage shortly before half-time on a huge occasion with the new Premier League champions eyeing more silverware.
Eagle-eyed fans spotted that Pep Guardiola's side were wearing an unusual shirt for the occasion - with an intriguing explanation for the change.
Unlike Watford, City did not have the FA Cup affiliation patch on their sleeve, reportedly due to the fact it advertises competition sponsors Emirates, rivals of City's main sponsors Etihad Airlines.

Having been given permission to omit the patches, City instead opted to edit their sponsors logo in response - with "Choose Etihad" emblazoned across their shirts.
The kit sponsor usually says "Etihad Airways" - with the change appearing to be a direct response to the rival advertiser sponsoring the competition.
