Brad Friedel believes he can play on for many years to come and puts it down to the science used on players now.
The American ‘keeper went to Spurs in the summer, and has already ousted Brazilian Heurelho Gomez as Harry Redknapp’s first choice at White Hart Lane.
The former Liverpool man turned 40 in May, but feels as though he can go on playing for a number of years more.
“If you can keep yourself free of major injury and you want to keep playing, then you can go much longer than an outfield player could," he said.
The former USA international has now made 277 consecutive appearances in the Barclays Premier League, which includes spells with Blackburn and Aston Villa, amongst others.
Friedel believes improved training methods and physiological sciences have been the key behind playing so long, as well as what will allow him to keep playing.
He said: "These days with all the focus on nutrition and health, together with the less distance we have to cover in training and in matches, why shouldn't a goalkeeper play well into his 40s?
"My body doesn't feel the way someone might think a 40-year-old should feel.
"I don't wake up every morning and think, 'Oh no, I'm 40, I don't feel like training today'."
The Spurs man has been impressive in his side’s recent run of nine games undefeated, which has seen them climb to third in the league.
He thinks it is down to belief: “It can be done if you want it - and I do.”
