With Tribalfootball present, an 81st minute winner from Armando Broja secured the win in what was a tight game where both sides struggled to create openings.
The win took Chelsea top of Premier League 2 Division 1 and left Spurs ten points adrift of their rivals.
"It was a game of very few chances, both teams if we're being honest lacked a little bit of quality in the final third," Burnett said after the game.
"I thought we had the slightly better chances or were in the better positions but didn't really capitalise, I thought only one goal would win it and I'm really disappointed that we haven't at least come away with a draw – I think a draw would have been a fair result."
Spurs did create a few decent openings in the first half and were definitely on top early on, but their final pass was too often lacking.
Chelsea then began to take control of the match and were the more dangerous side in the second half.
"There were some positives to take from it in terms of performances but we've come away without scoring and having conceded," Burnett added.
"At times we played well, created, dominated the ball at times but there were limited chances for both teams, we haven't defended well enough on that action and we've conceded so we're very, very disappointed."
