Chelsea manager Maurizio Sarri has wasted little time in confronting second assistant Marco Ianni after he incited a touchline bust-up during a dramatic finish to the 2-2 draw with Manchester United.
Ianni celebrated Ross Barkley's stoppage-time equaliser for the Blues in front of the visiting bench at Stamford Bridge, much to the annoyance of Jose Mourinho.
The United manager had to be restrained by stewards as tempers flared in the aftermath to the late goal, though Sarri insisted he did not witness the incident.
