Foxes still able to keep pace
Spurs 0 Leicester 1
Robert Huth's late header proved enough for Leicester to beat Tottenham at White Hart Lane and draw level on points with leaders Arsenal.
The two sides were meeting for the second time in four days after their FA Cup third round tie at White Hart Lane ended in a draw on Sunday.
This game looked to be going the same way until Huth headed home his first of the season eight minutes from time to give Claudio Ranieri's side the three points.
With Arsenal conceding a last-gasp equaliser at Liverpool, second-placed Leicester, who had not scored a league goal in over six hours, are only kept off top-spot by an inferior goal difference.
Despite recalls for Tottenham's Harry Kane and fit-again Jamie Vardy - one of nine changes for Claudio Ranieri's visitors from the weekend's game, neither could get their names on the scoresheet.
It was the hosts who started the quicker with Christian Eriksen's attempts at replicating his opener drawing a simple save from Kasper Schmeichel.
He then played in Dele Alli, who came close to celebrating his new White Hart Lane contract with the opener but could only send his rasping shot wide.
Schmeichel was called into action to make a much more meaningful save as Toby Alderweireld headed Erik Lamela's corner into the ground, with the Leicester stopper diving to his right to claw the ball behind.
The Foxes' first decent chance of the night came as Hugo Lloris' poor clearance ended at the feet of Vardy, who charged into the box before teeing up Shinji Okazaki only for the Japan forward to fire wide. They came even closer as the half-hour approached, this time Lloris was the saviour as he stretched to tip Danny Drinkwater's angled volley around the post.
Tottenham's England man was to come within inches when as Kane latched onto Erik Lamela's pass but saw his effort turned onto the crossbar by Schmeichel, before Alli's follow-up was blocked behind.
But no-one could get in the way of Huth's powerful header as the former Chelsea and Stoke defender guided Christian Fuchs' corner beyond Lloris to claim another big win for Ranieri's men.
