Two sublimely headed goals by Dele Alli was what it took for 5th placed Tottenham to offset league leaders Chelsea.
After the game looked like it was heading for a 0-0 draw going into half time with both sides playing tactically for majority of the first 45 minutes, the break came in for spurs on the brink of half time when Christian Eriksen was given the freedom to float in a sweet cross into the 18 yard box and on the end of it was in-form Midfielder Dele Alli who headed the ball home to end the half with the scales tilting in favor of the home team.
Upon resumption of the second half, the blues were the first of both teams to come out of the tunnel. Conte's men started brightly with the Spurs defence doing well to fend of threats from Costa and Hazard.
It didn't take long for the blues to lose concentration again, giving Eriksen the chance to swing in another beauty which fell nicely on the head of Alli who converted home on the 54th minute for his second of the night.
With a 14th straight win in sight as well as the chance to break a premier league record by becoming the first team to win 14 consecutive league games, Chelsea were outdone by a determined Tottenham side who now rise from 5th to 3rd position toppling Arsenal and Man City in the process.
