Antonio Rudiger was sent home from training on Sunday after he came to blows with Chelsea team-mate Kepa Arrizabalaga – the club’s second bust-up in 24 hours.
Thomas Tuchel’s unbeaten start as Blues boss came to an end on Saturday as West Brom secured a shock 5-2 win at Stamford Bridge.
It shone a light on Chelsea’s defensive frailties but their manager urged them to remain calm.
Despite Tuchel’s plea two of his players were involved in a heated argument that eventually got physical with the pair pushing each other.
Rudiger was sent to the changing room to calm down with the incident starting after he came in late on Arrizabalaga during a training game, reports the Telegraph.
The Spanish goalkeeper completed the session with Tuchel adjudging him to be in control of his emotions, but didn’t feel similarly about his compatriot.
Rudiger was reportedly not calming down quick enough and was subsequently sent in early.
The defender has since apologised to Arrizabalaga and Tuchel is content to draw a line under proceedings.
Emotions are certainly running high at Chelsea following their shock loss on Saturday, a defeat that could seriously hamper their top four ambitions.
Club captain Cesar Azpilicueta and Reece James are said to have been involved in a heated discussion in the aftermath of the West Brom defeat.
James was partially to blame for the Baggies second goal as the Blues’ defence fell apart following Thiago Silva’s red card.
The skipper and the right-back have since spoken in private as they attempted to settle their differences and there was no issue between them in training on Sunday.
Chelsea’s defence had been a strength since Tuchel arrived and they will have to address any issues before Wednesday’s Champions League game with Porto.
