The Blues boss was visibly angry as he walked out of training on Tuesday, about 24 hours ahead of the club's Europa League final against Arsenal.
The Italian could not hide his frustration as he made his way back to the changing rooms, throwing and then kicking his cap as he stormed off the pitch.
Sarri's antics followed a clash between Chelsea players Gonzalo Higuain and David Luiz, according to BBC Sports.
Chelsea have since insisted, though, that the coach's reaction was "not related to any of his players", and that he was simply unhappy "due to not being being able to practise set-plays" because the training session remained open to the media.
There has been speculation over Sarri's future at Stamford Bridge, especially as he is heavily linked with Italian champions Juventus.
The Europa League final will take place in Baku on Wednesday night, and the game will kick off at 21:00.
