Leicester striker Jamie Vardy is being replaced - that's five games without a goal for him - Leonardo Ulloa comes on.
And Spurs make a switch too, Christian Eriksen comes off for the slightly less creative midfielder Mousa Dembele.

John Nixon: Lloris posted Walker's bail there, amazing goalkeeping!
SPURS HIT THE WOODWORK
This is the chance of the game. Erik Lamela plays the ball into Harry Kane, whose shot is saved onto the crossbar by Kasper Schmeichel. Great save by the Leicester keeper.

Kyle Walker gifts the ball to Jamie Vardy - not for the first time tonight - with a woefully under-hit backpass and keeper Hugo Lloris comes running out to take the ball and Vardy out. Some fans wanted a penalty but it was never a foul.

Leicester winger Marc Albrighton looks furious with someone - presumably himself - as he runs the ball out for a throw-in needlessly. This hasn't been a classic.

This might be the closest Spurs have come as Ben Davies runs down the left and picks out Erik Lamela, but his shot from about 12 yards out is deflected wide. He should probably have finished.

Spurs have a free-kick as Wes Morgan bundles over Harry Kane but Christian Eriksen's shot is straight into the wall. Hard to know what he was trying to do there.

Leicester's Christian Fuchs plays a one-two with Riyah Mahrez from a corner and plays it to Danny Drinkwater, whose 25-yard shot is deflected out for another corner.
The second corner ends up at Jamie Vardy's feet 10 yards from goal but his shot is deflected over. That was his first sniff of goal.

With Arsenal and Manchester City both drawing at half-time, it's as you were in the top four (although with everyone having an extra point).
HALF-TIME - Spurs 0-0 Leicester
Both sides have played all right but neither team have been great. Not a classic but not the worst game either.

Quote Message: The return to fitness of Mousa Dembele, with a bit of strength, he can carry the ball and shoot from distance. He might be considered on the hour mark by Spurs.
