In a supposedly nervy encounter involving the two best defence in the Premier League this season, it was the 20yr-old double header that gave the host the maximum points.
The England midfielder of Nigeria descent found the back of the net either side of the interval to make it seven goals in his last four matches
The game started at the White Hart Lane with both Chelsea and Tottenham trying to lay claim to the possession, but it was the Blues that got the first chance of the game in the fifth minute when Eden Hazard hit wide a Nemanja Matic's lofty pass.
After dominating the possession for the majority of the half, Spurs turned it into a goal in the added minute of the first half through a Christian Eriksen cross which was perfectly placed into Courtois' goalpost by Dele Alli.
His second goal of the game came in a similar fashion in the 54th minute with Christian Eriksen also putting up another impeccable cross for Dele to nod into the net having found space between Victor Moses and Cesar Azpilicueta.
Mauricio Pochettino's side who are also enjoying a purple patch of their own, having won five from five since losing at Manchester United won the game and with that they put an end to Antonio Conte's team 13-match winning run. The last time the Blues lost a game was also in North London, losing 3-0 to Arsenal in October.
With the win, Tottenham are now third on the log just above Manchester City on goal difference but reducing the point between themselves and Chelsea to seven points.
