Guardiola was involved in a sarcastic handshake with Oliver after a controversial decision helped Liverpool beat City 3-1 in their key Premier League title race clash.
The City boss sought out Oliver on the pitch following the defeat at Anfield, which leaves his side nine points adrift of Jürgen Klopp's men, and was clearly picked up on TV cameras saying: “Thank you so much! Thank you so much!"
The decision in question came less than ten minutes into the game, as City were denied a penalty when the ball struck Trent Alexander-Arnold on the arm inside the penalty area.
