Mourinho said: “My coaching staff do not need contracts. They never need a contract.
“They only need a contract when they decide to stop working with me. When they want to work with me, they know they have an automatic contract because where I am, they are.
“They don’t need a contract. They just need to speak with the club for 10 minutes and to sign a document, you can call it a contract, but for me the contract they have is with me.
“They have a contract with me since I started my career as a manager. They have worked with me since then but my Portuguese group are together and know that wherever I am, they will be with me as well. There is no problem. They know that when I have a job, they have a job. They have no problems.”
On his own future at the club, Mourinho added: “I think it is difficult to be a manager after me at any club so I would not recommend it.
“I know the list is quite long – 11 or 12 managers of Chelsea – but even if the list becomes bigger it is no problem for me. I am cool but it is my desire to stay at Chelsea.”
