Chelsea boss Jose Mourinho has told the club's new director of football, Avram Grant, he won't tolerate interference.
Mourinho said: "The club want to bring some support to different areas and as long as he does not interfere with the power I have in my job then it is fine.
"The club was very clear in their statement about his role.
"It's not my job to speak about him. He will have to speak for himself."
The Blues boss also confirmed that left-back Wayne Bridge has an injured hip.
Mourinho added: "Wayne has a problem with his hip and we don't know yet how serious it is."
