Although they have slipped to seven points behind Leicester City after only managing a draw against Liverpool at Anfield, Mauricio Pochettino's side have been fully in the running at the top of the table for the majority of the season.
Led by Harry Kane's 22 goals, Spurs are on course for their highest league finish since 1963, when they finished second two years after their historic double-winning triumph.
King, who made all 321 competitive appearances of his professional playing career with the North London club, hailed the team spirit of the club under Pochettino and insisted that the current generation of Spurs stars can be consistent title challengers.
The 35-year-old told talkSPORT: "I’m really pleased with the Tottenham team at the moment, I’m really pleased with what they’re doing and how the future’s looking.
"It’s been such a team effort. In seasons past we’ve always had these individual stars, but the team as a whole has been the big factor this season.
"I’m seeing all the right signs that this is a team, not just for this season but for the future, that has the right mentality and can hopefully win the Premier League for the next few years to come."
Pochettino's Spurs definitely have the steel for a title challenge, having lost only four Premier League matches all season long whilst juggling domestic cup and Europa League commitments.
It remains to be seen how they will cope with the Champions League qualification which looks almost a certainty, but if they can reinforce in the summer and add that extra level of quality to their squad, there is no reason why they should not be able to repeat the success of this campaign.
Spurs host an improving Manchester United at White Hart Lane on Sunday as they look to keep their slim title hopes alive.
