England midfielder Dele Alli is going through a bit of a warm up.

Could Spurs sacrifice Eric Dier or Victor Wanyama in order to give themselves a bit more of an attacking threat?

Harry Kane throws himself at an Eric Dier cross into the area but his diving header is just wide.

Vincent Janssen brings down Wilfried Zaha as Palace look to launch a counter.

The Dutchman is warmly applauded for his efforts in what has been an encouraging first start from the 22-year-old.

Spurs have started this second half on the front foot.

Spurs have had more of the ball but as the above graphic shows they haven't had it in dangerous areas as often as they'd like.

It's goalless at the break but it's been pretty entertaining as these things go.

Spurs have had the better of the chances, with Palace keeper Wayne Hennessey forced into good saves from Toby Alderweireld, Harry Kane and Vincent Janssen.

The Eagles have looked fairly comfortable in possession but are yet to have a real shot of note.

Palace have now failed to score in the first half of their last nine Premier League games.

Harry Kane blasts wide from 20 yards after some good build-up play.

A couple of Spurs fans have to take some swift evasive action.

Palace getting back into this here.

The Eagles have been second best for much of the first 45 minutes but have just started to get their foot on the ball now.

Spurs win another corner and again Toby Alderweireld is left unmarked.

This time the Belgian can not direct his volley on target. Again, the Palace marking looked, at best, not great.

Another stoppage for some treatment here as Eric Dier is down with a groin injury.

Connor Wickham smashed the ball straight at his, well... groin from about two yards away.

England manager Sam Allardyce is at White Hart Lane today.

As well as Tottenham's England regulars, could he be having a look at Palace skipper Scott Dann?

Palace skipper Scott Dann is just getting a bit of treatment after a strong, but fair challenge from Vincent Janssen.

Janssen has looked impressive so far.

Quick bit of housekeeping, Palace winger Wilfried Zaha was the first player in the book after a late challenge on Spurs defender Toby Alderweireld a moment or two before those Hennessey saves.

Zaha has now been booked in both games this season.

Great work by Wayne Hennessey keeps the scores level.

The Wales international gets down well to save Harry Kane's deflected effort from outside the area before getting up to deny Vincent Janssen on the rebound.

Palace defenders get back to block Janssen's second effort.

Victor Wanyama heads over from an Erik Lamela corner.

It was certainly more difficult than the Toby Alderweireld chance earlier on but Alan Pardew will not be pleased to see Spurs winning headers so easily from set pieces.

Crystal Palace force a couple of corners in quick succession but they come to nought.

Christian Eriksen leads the Spurs counter but dwells on the ball too long with Erik Lamela wide open to his left.

The Argentine, understandably, is not overly impressed.

Harry Kane links up with Vincent Janssen for the first time but the Dutchman's curling effort is high and wide.

Could this be the start of a beautiful partnership?

Spurs are just starting to get into this now.

Erik Lamela's corner is met by Toby Alderweireld but the Belgian international could only direct his header straight at Palace keeper Wayne Hennessey.

Moments later Hennessey has to cut out Harry Kane's low cross.

Victor Wanyama's cross into the box is too close to Palace keeper Wayne Hennessey.

Harry Kane, for those interested, is playing in a slightly more withdrawn role today. Vincent Janssen, on his full debut, is in Kane's usual position.
