Pep Guardiola was involved in a furious row with Nathan Redmond following Manchester City's dramatic 2-1 win over Southampton on Wednesday night.
Raheem Sterling scored a dramatic injury-time winner at the Etihad Stadium as City extended their lead at the top of the Premier League to eight points - and their manager celebrated the goal wildly.
However, he came on the pitch after the full-time whistle and put his arm around Southampton forward Redmond to speak to him.
The pair were then captured on camera exchanging angry words with Guardiola gesturing wildly in the face of the player.
A smiling Redmond covered his mouth as he uttered some words, prompting more anger from the City boss.
Discussing the incident with Sky Sports afterwards, Guardiola said: "No discussions. We just talk about how good a player he is and how quality he is.
"Redmond and Sofiane Boufal are players who today just defended, but they are players with a lot of quality."
