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.
