Gianfranco Zola has revealed Chelsea intend to file a complaint after Maurizio Sarri was left "offended" by a comment made by one of Burnley's coaching staff in the fiery 2-2 draw at Stamford Bridge on Monday night.
Sarri was sent off in the dying stages of the thrilling contest, which triggered off a touchline melee involving the injured Antonio Rudiger and members of Burnley's coaching staff before Ashley Westwood and David Luiz went head-to-head outside the players' tunnel.
Sarri, who is set to miss Chelsea's next match away to Manchester United, subsequently chose not to appear at his post-match press conference, which Zola explained was down to the Italian's frustration at being "offended" by something he heard from the visiting bench.
"The reason is he's very frustrated, so he'd prefer not to come over here. He's been sent off," Zola said.
""I think he's been offended as well, so he didn't feel it was the right thing to do, to speak to you.
"I know you wanted him, so I'm sorry. But you can understand: he's frustrated at the game, frustrated at being sent off, and the other thing. He'd prefer not to come in.
"I think he's been told something from their bench, but don't ask me exactly what. I don't want to go down that line, but we'll see what we can do about that.
"I think there will be a follow (up) on that. Maurizio felt very unhappy. We understand it's a football game.
"You say words because of the adrenalin, but he wasn't particularly happy. If Maurizio said that, probably it's something that could have been avoided."
