Chelsea began a Premier League managers' tribunal on Thursday, with hopes of resolving Antonio Conte's compensation claim for a £9 million severance package relating to his contract with the Stamford Bridge side.
The former Blues boss was sacked last summer despite having one year remaining on his contract. As a result, the Italian is asking to be paid in full the wages he would have earned during that final season in London.
Chelsea's case will dispute Conte's version of events, citing a breach of contract due to some of the former Italy national team manager's behaviour in the final year of his time as the club's head coach.
Diego Costa left Chelsea for £57m in January 2018 after the striker's relationship with Conte broke down, with the latter informing the former via text message that he was no longer wanted by the team.
The club will point to that gesture as an example of the trainer's lack of professionalism.
A three-person panel has been appointed in an undisclosed location and a verdict is expected soon, although there is no time frame set for the trio of individuals to come to a decision.
