Chelsea boss Jose Mourinho has claimed that he will still have an appetite for top-level management in 20 years time.
The Portuguese, 52, is considered one of world's finest managers, having won 18 major trophies in four different countries - including two Champions League titles.
However, Mourinho, whose first job as a head coach came with Benfica in 2000, warns his contemporaries that he will only improve as a result of accumulated experience.
"I see myself going into the seventies - not for ever and ever but while my health is good," he told reporters.
"It is a job where experience is very, very important. With players, there is a moment when their experience has a fight with their physical condition.
"With managers, no. Unless you lose your appetite then that is a different story but I see myself now better than I was 10 years ago. I am in evolution, not even in stability."
Mourinho first joined the Blues in 2004 after leading Porto to Champions League glory, but left in 2007 and returned in 2013 following spells with Inter Milan and Real Madrid.
