Manchester United legend Patrice Evra clashed with Manchester City staff after the Blues' Champions League victory over Real Madrid.
The former defender, dressed in an all-red suit, was at the Etihad working as a TV pundit on Wednesday night.
But Evra was involved in an altercation with City coaches on the pitch after the final whistle and had to be calmed down by Pep Guardiola's assistant Manel Estiarte.
The fracas happened as City players celebrated thrashing holders Real Madrid 4-0, winning 5-1 on aggregate.
Evra, 42, remonstrated with Estiarte near his former team-mate Rio Ferdinand and his BT Sport colleagues.
Evra later told CBS Sport: 'He was looking at me, he was like 'this is for you! This is for you!
'So I came close and asked him why he was so agitated and he said 'no because last year you said on TV that they [City] s*** themselves, that's why they lose', and this year they didn't s*** themselves.
'That's the truth Micah [Richards]! You know I'm an honest man I'm straight and after he apologised.'
The City boss held the Frenchman by his arms and appeared to be successful in calming him down.
The pair then shook hands before going their separate ways.
