Manchester United boss Ole Gunnar Solskjaer clashed with counterpart Pep Guardiola during victory at Manchester City on Sunday.
Solskjaer entered Guardiola's technical area to confront his opposite number during a heated altercation in the Manchester derby.
Solskjaer's United scored early in both halves on their march to a 2-0 victory at the Etihad, with Bruno Fernandes scoring a second-minute penalty and Luke Shaw doubling the advantage in the 50th minute.
The dispute started when City players refused to give the ball back to United after Marcus Rashford's injury prompted Dean Henderson to knock the ball out of play.
Rather than give possession back to United, the hosts took the throw-in quickly, leading to a frank exchange of views between Guardiola and Solskjaer.
The two managers initially appeared to make up with a fist-bump only to continue quarrelling moments later.
The bickering continued for another minute before a second fist-bump restored peace between the two dugouts, reports the Mirror.
