Pep Guardiola reacted angrily to suggestions Manchester City's historic Treble has been tarnished by UEFA's Financial Fair Play investigation.
City became the first English club to complete a domestic clean sweep after demolishing Watford at Wembley, clinching their sixth FA Cup trophy and first since 2011.
The six-goal hammering was the largest in 116 years and there was confusion as to whether Raheem Sterling became the first man since Blackpool's Stan Mortensen in 1953 to score a hat-trick in a cup final.
Gabriel Jesus was awarded City's goal after his shot trickled over the line but only after the full-time whistle had been blown.
