The Blues team-mates appeared to go head-to-head during a training session and Sarri was later seen storming from the pitch in apparent anger.
However, the Italian claimed he was annoyed by the presence of media preventing his side from being able to practice set-pieces.
Gonzalo Higuain and David Luiz clashed at Tuesday’s session and atmosphere seemed tense
Argentina ace Higuain looked displeased as he spoke to Luiz in the aftermath of the incident
Maurizio Sarri insisted he was not concerned by the behaviour of his players in training
He told BT Sport: ‘I think that you were not able to understand yesterday. If my players are really very aggressive in training i am happy, not disappointed.
‘I was disappointed because we wanted to try out solutions on set pieces. But after 50 mins of training the camera were there.
‘So we were disappointed for the situation not for the players.’
Despite Chelsea’s attempts to play down the row, Luiz did seem to throw his left arm towards Higuain’s face in an aggressive manner.
Higuain ran towards Luiz from behind and the Brazilian defender reached back and made contact with the striker’s face.
Argentina international Higuain was displeased and grabbed Luiz’s elbow as he spoke with him in the aftermath.
