But a largely uneventful first half ended with a familiar face putting Leicester in front, Vardy firing home from 12 yards in the fourth minute of stoppage time after Serge Aurier had barged into the back of Wesley Fofana just inside the area.
But Leicester was gifted a second on the hour when Vardy's header across goal was deflected into his own net by Alderweireld, who was under no pressure.
Writing in his column for Metro, Berbatov said: "Leicester have had lots of ups and downs so far, you expect them to win a game and then they lose, and when you expect them to lose a game they win".
"I'm frustrated when I lose but it's not like there is a target that can not be achieved".
"It was a mistake, not a moment of madness", he told Sky Sports.
Spurs are second in the table with 25 points, three behind leaders Liverpool.
"It obviously shows we're doing something wrong in our home games".
"We did it at Porto, Inter, Real [Madrid], Chelsea, both times, we did it without that need of that longevity and also my desire to try different things and my insane desire to go to many countries, and to try to win it, and try to get different experiences in many different countries, was ideal because was about winning, and goodbye, and let's try another thing".
