Chelsea boss Maurizio Sarri clashed with Cesar Azpilicueta last week, it has been revealed.
The Blues were beaten 2-0 at the Emirates on January 19 and it is claimed the duo had some choice words when the players and staff met for a team meeting on Monday.
The Times says the Spanish defender, who has been Chelsea captain for large parts of the season, spoke out against Sarri's brutal criticism of the team in his post-match press conference.
