The pressure of performing is already there on Chelsea manager Jose Mourinho from his club as well as fans, and now it has increased after former Chelsea team doctor Eva Caneiro has reportedly sued the Portuguese coach.

The Press Association broke the story this afternoon that the Chelsea boss may have to go through an employment tribunal for the same or seek out-of-court settlement.

Notices will be served on Mourinho this week as part of separate but connected claim against him and the club. 

It is alleged that Carneiro's lawyers are already suing the club for the treatment meted out to their client by the ex-Real Madrid manager in August this year.

Carneiro, along with Chelsea physio Jon Fearn, administered treatment to Eden Hazard after the forward picked up a knock in the closing stages of Chelsea's 2-2 drawn match against Swansea on the opening day of the Premier League this season.

Chelsea were temporarily reduced to nine men as the duo rushed to the field for treatment, and the action attracted the wrath of Mourinho, who called both Fearn and Carneiro as impulsive and naive and lacking in football knowledge.

It was reported by the BBC only in September that the 42-year-old, Gibraltar-born British sports medicine specialist was seeking advice from a London law firm over the past few weeks and was considering legal options.
