Eagle-eyed fans claim Pep Guardiola told Eddie Howe that it wasn't Newcastle's usual style of play during their FA Cup meeting on Saturday evening.
Manchester City progressed to the semi-finals at Wembley after their 2-0 win over the Magpies at the Etihad, with Bernardo Silva getting both goals from deflected opportunities.
But some fans believe that the Man City boss was quick to query why Newcastle weren't their usual selves during the game, asking Howe about it at the final whistle.
Fans believe that Guardiola spoke to Howe and his assistant Jason Tindall during their post-game handshake to say: 'That's not how you usually play football'.
