Jose Mourinho has been speaking about the injury that forced Chelsea goalkeeper Thibaut Courtois off before half-time against Arsenal.
The Belgian international suffered a blow to the head in a collision with Alexis Sanchez and he was later replaced by Petr Cech.
Courtois has since been taken to hospital, but speaking after Chelsea's 2-0 win over the Gunners, Mourinho calmed fears over the severity of the injury.
In comments published by Chelsea's official Twitter account, the Portuguese boss said he was worried about Courtois in the immediate aftermath of the blow and that he went to hospital as a precaution.
However the Blues boss said, there is "nothing to be too much worried about."
Hopefully that means Courtois will soon be back in action and that he has not done any serious damage following the clash.
The Blues went on to win the match courtesy of a penalty from Eden Hazard and a lob from Diego Costa.
Jose says he was worried for Thibaut Courtois, one of the best goalkeepers in the world, after his injury. #CFC— Chelsea FC (@chelseafc) October 5, 2014
