Maurizio Sarrri walked out of a Chelsea training session on Tuesday ahead of this evening's Europa League final against Arsenal at the Olympic Stadium in Baku.
The Chelsea manager threw his baseball cap to the ground and kicked it as he stormed off the pitch with the media looking on.
It came after a row had begun on the pitch between Gonzalo Higuain and David Luiz which appeared to start after the Argentine striker had made a challenge on the Brazilian defender during a training match.
"It does raise concerns," former Chelsea forward Eidur Gudjohnsen told BT Sport as he sat in studio watching the session.
"Something must have gone on.
"You obviously have a group of players with big personalities and the last thing you need or want is for your players to get injured.
"Looking at the training session, the last 15 - 20 minutes [have been] rubbish, a waste of time. Players are just standing around, something went on and sort of ruined the training session, that is what it looked like from here, anyway.
"You don't want to see your players arguing, that's for sure.
"You want a well-organised, short, sharp training session, 45, 50 minutes just reminding everyone of their tasks, getting the muscles ready, getting everyone hungry for tomorrow's game."
Tempers fraying in the Chelsea camp? 😡
