Andre Villas-Boas has played down talk he could stay at Chelsea for the rest of his career, admitting he had expected to be at Porto for many years.
Blues chairman Bruce Buck last week declared the club may finally have found their Sir Alex Ferguson figure in Villas-Boas, claiming the 33-year-old could end up staying at Stamford Bridge for 15 years.
"It's the 14th October, which is the day I started at Academica," said the precocious Villas-Boas as he celebrated the second anniversary of his entry into football management on Friday. "I have this idea of not being in the game for a long period of time. Bruce's words weren't said to collide with my words, on my future, but I really don't know what will happen."
Villas-Boas is Chelsea's seventh manager in the eight years since Roman Abramovich bought the club, with the Russian ruthlessly dispensing of those he deemed to have failed in the job.
The Blues are also on their 15th boss since Ferguson took charge of Manchester United almost a quarter of a century ago and Villas-Boas admitted it was "difficult to imagine" spending a similar length of time with one team.
He added: "It would be difficult for Alex to have predicted that 25 years ago."
Buck last week gave Villas-Boas a ringing endorsement, revealing Abramovich was particularly pleased with the attractive brand of football the new manager was beginning to implement. But Buck also seemed to acknowledge success had to follow if the Portuguese was not to suffer the same fate as most of his predecessors.
Villas-Boas said: "A longer or shorter stay can or cannot be related to success. Last year, I went through the same (at Porto). We won four trophies and my emotions told me I'd be there a long time. But now I'm here.
"From what I understand from the chairman, there's confidence in the work we're doing and the most important thing is for me to alert people who aren't at the club that it isn't my arrival that's made us start well.
"This is a group success. We're happy with what we're achieving. Not fully happy because we'd like to be first in the league. But we're confident for the future."
