Maurizio Sarri appeared to storm out of training on the eve of Chelsea's Europa League final against Arsenal in Baku.
The Blues manager threw his club baseball cap to the turf, kicked it, picked it up and threw it down again, before walking down the Baku Olympic Stadium tunnel.
Chelsea were approached for comment on the matter, which came just hours after Sarri had revealed the growing love for his players amid rumours surrounding his long-term future.
Sarri has already led Chelsea to next term's Champions League courtesy of a third-place Premier League finish, but doubts remain over his tenure after an often fractious first campaign in London.
"The beginning of the season was really very difficult for me to understand my players, the mentality," said Sarri.
"But after a very difficult month in January, in February they started to change, I think, probably I changed, I don't know.
"In this moment I love them, because I have 20, 22 wonderful men and wonderful players. So now I am really very happy with them.
"And of course I have to consider it for the future. And I have to consider that I love English football, I love the Premier League."
Asked if he could end up at Juventus next season, Sarri added: "I want to think only to the final of course, then I have a contract with Chelsea for two years."
