Tottenham manager Harry Redknapp has extended his contract with the club until 2013.
His deal was due to expire in 2011 but included an option for a further two years which the club have exercised.
"I am now committed to Spurs for the next three years and of course I am pleased by that," Redknapp told ESPN.
"That has made me think about how long I want to stay in the game and - who knows - I might stay with Spurs many more years than 2013."
The 63-year-old guided the club to fourth place last season, their highest Premier League finish and earning them a place in the Champions League.
He also won the Premier League Manager of the Season award.
"You never know what is around the corner and, while I have the energy, I think I will carry on for as long as I can," Redknapp added. "I feel as though I have a good few years left me in yet.
"When you see how long [the 68-year-old] Sir Alex Ferguson has lasted, and then look around at some of the guys of the older generation that keep on going like Fabio Capello (64), Arsene Wenger (60) and Roy Hodgson (62), you think 'I could do the same'.
"None of them are youngsters any more, they are of the same age group, and it is true that there is no substitute for experience in management. The game is crying out for stability, and the experienced guys know the job, and for so many now age is not a problem."
Redknapp left Portsmouth to take over as Spurs boss in October 2008 and guided them from the bottom of the league to an eighth-place finish.
Under his predecessor Juande Ramos they had had picked up just two points from their opening eight games - their worst ever start to a season.
But Redknapp soon turned their fortunes around, guiding them to safety and helping to earn them a place in the League Cup final which they lost to Manchester United on penalties.
Redknapp began his managerial career at Bournemouth before taking over as West Ham and then a first stint with Portsmouth.
He left Fratton Park to join rivals Southampton but he lasted less than a year, returning to Portsmouth, where he led them to victory in the FA Cup final in 2008 - the club's first major trophy for 58 years.
