Dr Carneiro was associating herself with the first team in a way discouraged by the club for backroom employees, Chelsea's legal team added.
hmmmm, So the rumours of an affair with a first team player are most likely true. Thats how I read that sentence.
My money is Ivanovic, definitely, always said there was something between them two.
To be honest though, my opinion on this is as follows:
Rumours going around the first team that she was sleeping with one of the players, this pissed Jose off.
He took it out on her and found an excuse to demote her (The Swansea game). I believe this to be the case because I have never seen a manager go after a doctor like that for treating a player, and the ref called the doctors onto the pitch, so she had a duty of care to offer treatment to Hazard. Jose must know this, he has been a manager for 15 years, he must know how club doctors work. This was all a ruse by Jose to get rid because he probably thought she was corrupting his player(s).
The club were probably also aware of the rumour and so silently backed Jose because they wanted her out too.
This is my take on what happened.
