The tension boiled over for Maurizio Sarri as he twitched and drew on his fake cigarette, fought a running battle with Burnley's coaching staff and was dismissed from the touchline in the closing seconds of a frantic draw.
Sarri was ordered down the tunnel by referee Kevin Friend and his backroom team became embroiled in a series of arguments with Sean Dyche's staff at the final whistle.
Antonio Rudiger, injured and unable to play, was also involved as things turned ugly at the end.

Burnley had dug in and fought hard for the point which will ensue they are playing Premier League football for a third successive season.
They were delighted with the result at Stamford Bridge.
Chelsea were frustrated by another missed opportunity; a chance to put pressure on others allowed to slip by despite dominating the contest.
Yet, with Tottenham, Arsenal and Manchester United all misfiring in the Premier League, they remain firmly in the hunt for the top four and in the semi-finals of the Europa League.
Sarri was ordered to lead them back to the Champions League and two routes remain open.
Although this was a setback deepened by concerns over an injury to Callum Hudson-Odoi who was forced off in the first half.
And the strain was on display as Sarri became embroiled in a running dispute with the Burnley coaching staff and Gonzalo Higuain reacted angrily when hauled off in the closing stages to be replaced by Olivier Giroud.
Higuain had performed well and scored his team's second during a frantic first half-hour which was triggered by Jeff Hendrick's brilliant strike which gave Burnley the lead in the eighth minute.
