The 40-year-old goalkeeper has arguably been Spurs boss Harry Redknapp's most impressive acquisition over the past twelve months, with his consistency between the sticks a key component in the club's title tilt this campaign.
"Brad has been unbelievable," Jennings told the club's official website. "At his age, to be on a run of approaching 300 matches without missing a game is fantastic.
"I don't think anyone will ever get near that record."
Friedel has kept eight clean sheets in 22 league matches since arriving at White Hart Lane, helping Spurs to third in the table on 46 points. The run has added to his personal record of 288 consecutive starts in the Barclays Premier League, dating back to the start of the 2004-05 campaign.
Jennings, who made 590 appearances for Tottenham between 1964-77, winning the FA Cup, two League Cups and the UEFA Cup, appreciates more than most the value of experience at the back, and has backed the American to play on for some time yet.
"I was 41 when I played my last game [for Northern Ireland] against Brazil," he added. "In fact, that was on my 41st birthday.
"I could have played on if I had the opportunity, and there is no reason why Brad can't continue to play.
"He's been brilliant for us. He's showed all his experience and just how good he is at the moment."
