Chelsea boss Jose Mourinho wants another 20 years at the top.
Mourinho is still only 51-years-old but is already one of the most decorated coaches to grace the game, having won titles in England, Italy, Spain and Portugal.
He said: "For me the situation is clear: I want to work, 15 or 20 more years. If, during this time, I do well enough to stay in a top level club, I will.
"If I don't do well enough, and my market changes and I only have smaller clubs waiting for me, I will. Because I repeat, I want to work if I'm physically and mentally strong enough - which I expect to be - for another 15 to 20 years."
