Pep Guardiola appeared to confront Dean Henderson after Crystal Palace were crowned FA Cup champions on Saturday.
Henderson played a key role in Palace's historical win, saving a penalty from Omar Marmoush after Erling Haaland had opted to give his strike partner the ball instead of take it himself.
There were questions over whether he should have been on the pitch at all, though, as he handballed outside the penalty area and survived a VAR call.
At full time, as Palace's players celebrated, Guardiola appeared to approach Henderson and cut a frustrated figure.
