Harry Kane tries a curling effort from outside the box but it sails high, wide and not so handsome.
85'
TABLE
If this result stays the same, Spurs are five points clear of Chelsea with just three games left to play - and one point behind Liverpool who have already played a game more than them. Watford, on the other hand, sit six points off the relegation zone with two matches to go - however a number of the teams around them still have three matches. They aren't out of the woods yet but they are pretty much safe.
83'
Substitution
Andre Carrillo (on). Will Hughes (off). (Watford)
83'
UNHAPPY
Will Hughes and Andre Gray are deep in conversation on the bench, looking very unhappy. I wonder if that's with each other or with the performance in general.
82'
Substitution
Erik Lamela (on). Dele Alli (off). (Tottenham Hotspur)
82'
FINAL CHANGES
Erik Lamela replaces Dele Alli for the hosts, with Andre Carrillo taking the place of Will Hughes. Richarlison will see this game out.
79'
STING GONE
That long stoppage for the injury to Richarlison means that some of the sting has gone out of this game.
77'
RELIEF
Richarlison is up and walking gingerly back to the touchline, but he has a nasty cut and is being evaluated for a concussion.
76'
WORRY
Now this is a concern. Kieran Trippier and Richarlison clash heads and the medical staff rush onto the pitch very quickly. Trippier is up and walking around but the young Brazilian requires some lengthy treatment.
74'
Substitution
Moussa Sissoko (on). Son Heung-Min (off). (Tottenham Hotspur)
74'
SPURS CHANGE
Heung-Min Son jogs off the field and Moussa Sissoko takes his place.
74'
OFFSIDE
Harry Kane slots the ball home and wheels away, but is correctly ruled offside.
8'
PRESSING
Spurs are starting to dominate here, putting Watford under pressure and forcing little mistakes. No goals as of yet.
73'
GOOD ATMOSPHERE
The Spurs fans are still in excellent voice - they haven't shut up since the start of this game. I wonder if they will miss Wembley?
71'
OFFSIDE
Gerard Deulofeu races through on goal and looks set to chip over Hugo Lloris, but is ruled offside.
70'
SO CLOSE
Jose Holebas makes a great run down the left and stands up a cross to the back post. Troy Deeney heads it down and Richarlison has the seemingly simple task of volleying home, but he blazes over the top. Woeful.
68'
OFF THE POST!
Jan Vertonghen rises highest to meet the free kick and his headed effort cannons back off the post. Harry Kane can't react quickly enough to turn it home.
67'
OUCH
Jose Holebas and Christian Kabasele combine to bring Harry Kane down - the England man grabs the back of his leg but should be OK to continue.
64'
Yellow Card
Victor Wanyama (Tottenham Hotspur)
64'
BOOKING
Typical. We've gone the whole game without a booking and literally seconds after coming on, Victor Wanyama earns a yellow card for catching Richarlison with his studs.
Victor Wanyama (on). Mousa Dembele (off). (Tottenham Hotspur)
63'
CHANGES FOR BOTH
Mousa Dembele seems to have picked up a knock and is replaced by Victor Wanyama. For Watford, Troy Deeney and Gerard Deulofeu are on for Kiko Femenia and Andre Gray.
62'
FRUSTRATION
Dele Alli rides two strong challenges from Craig Cathcart and Abdoulaye Doucoure before the referee signals a foul in his favour. The England man isn't happy with the treatment he's receiving.
60'
NOT MUCH TO SAY
There's a lot of hustle and bustle but not much real action. Spurs look more than comfortable.
57'
CHANGE NEEDED
Watford really aren't offering anything here and Javi Gracia may need to change something if he wants his side to have any chance in this game.
52'
WHAT THEY WANT
Spurs are able to get forward at will - it's like Watford only start defending when their hosts are in their box (or very close to it). This could turn into a big score.
48'
Goal
Harry Kane. Assist by Kieran Trippier (Tottenham Hotspur)
48'
WELL MADE
Tottenham don't need any help to make this one! Mousa Dembele holds off some challenges in midfield before turning and picking out Heung-Min Son with a lovely pass. Harry Kane slips and can't get on the end of his low cross but Kieran Trippier is waiting at the far side of the box, and Kane picks himself up to turn in at the second time of asking. Tottenham Hotspur 2 - 0 Watford.
48'
GOOOOAAAAALLLL
SPURS DOUBLE THEIR LEAD!
43'
WINDING DOWN
The first half is limping to a close. Spurs have the ball and don't look like they want to press forward, while Watford aren't keen to try and take it from them.
40'
FRUSTRATION
The Spurs fans seem a little frustrated that they haven't seen more goals. The hosts have dominated this game pretty much from the first whistle and if they don't get more goals, they could always be pegged back.
38'
FREEDOM
Richarlison isn't tracking back and it's giving Kieran Trippier the freedom of the park down the Spurs right. Jose Holebas has his hands full with Christian Eriksen and Trippier is causing some real problems.
36'
GOOD MOVEMENT
Watford string a good move together, with Richarlison producing some stepovers and Will Hughes pulling the strings. Abdoulaye Doucoure dances through the Spurs defence and gets a shot away, but Hugo Lloris saves with ease.
32'
ALL ACTION
Spurs are in complete control at the moment - Watford can't get a sniff. Harry Kane chips the ball into the box looking for the run of Dele Alli but Orestis Karnezis comes out to collect.
31'
CLOSE
Christian Eriksen tries an effort from distance which has Orestis Karnezis scrambling, but it bobbles wide of the post.
30'
CONTROVERSY
Heung-Min Son goes down in the area and virtually all of the Spurs players appeal, but referee Michael Oliver says no. That was a close call.
28'
GOOD DEFENDING
Heung-Min Son tries to cut inside down the left flank, but Craig Cathcart does really well to hold him off and win the ball back.
26'
GOOD SAVE
Etienne Capoue picks up on a loose ball in midfield and plays a superb ball into the path of Andre Gray, who can only find the legs of Hugo Lloris with his low shot.
23'
DANGER
Spurs' pace is causing Watford all kinds of problems. Jan Vertonghen picks out the run of Kieran Trippier with a long ball, he plays it on to Christian Eriksen, and his cross is cut out by Adrian Mariappa. Back to front in a manner of seconds.
21'
AMBITIOUS
Heung-Min Son knocks it back to Eric Dier, who fires over from 30 yards. Watford are offering very little going forward at the moment.
19'
ATMOSPHERE
Wembley was rocking before the goal, but now that Spurs have the lead the home fans are in great voice. Heurelho Gomes is not looking happy on the Watford bench following the mistake by Orestis Karnezis - the man who replaced him.
16'
Goal
Dele Alli. Assist by Christian Eriksen (Tottenham Hotspur)
16'
GIFTED
Orestis Karnezis won't want to see this one again! Kieran Trippier whips a wicked ball into the box and the goalkeeper spills it at the feet of Christian Eriksen, who controls it well before finding Dele Alli, who has the simple task of poking home. Tottenham Hotspur 1 - 0 Watford.
16'
GOOOOOOOOAAAAAALLLL
TOTTENHAM TAKE THE LEAD THROUGH DELE ALLI!
4'
EFFORT
Harry Kane gets a half-sight of goal from just outside the box, but his low shot is deflected into the arms of Orestis Karnezis.
3'
CAGEY
Both teams want to get hold of the ball and keep it - and so far neither of them have been able to do so.
46'
KICK OFF
The second period is underway. No changes from either manager.
45'
ADDED TIME
One minute is added on.
45'
HALF TIME
Dele Alli's easy goal separates Spurs and Watford at the break. Tottenham Hotspur 1 - 0 Watford.
90'
FULL TIME
Michael Oliver blows his whistle and the game is done. Tottenham have looked like the better side since the first minute - Watford have had their opportunities but never really looked like taking them, while Spurs could and arguably should have scored more. A simple Dele Alli goal following a Orestis Karnezis spill and a well-worked team move finished off by Harry Kane made the difference tonight, and Spurs can look ahead to the final few games of the season knowing that a top four place is all but assured. Tottenham Hotspur 2 - 0 Watford.
90'
GOOD SAVE
Andre Carrillo shows a good burst of pace to break through the defence and get a shot away, but Hugo Lloris is equal to it. Watford's hunt for an away goal continues.
90'
END TO END
Watford want to try and do something but it is too little, too late. And every time they come forward, Spurs look to hit on the counter.
90'
ADDED TIME
As I suspected, six minutes are added on.
90'
PETERING OUT
I suspect we're going to have a few minutes' of injury time following the clash of heads earlier, but I don't see the result changing here. Spurs have done a professional job tonight.
44'
FUMING
Well, here's some action! The Spurs defence get caught out by their own offside trap and Abdoulaye Doucoure races through on goal, only to see Hugo Lloris come flying out of his area to execute an inch-perfect slide tackle.
12'
ON THE BREAK
Watford aren't lying down here - they still have pride to play for, as well as the very faint spectre of relegation.
1'
KICK OFF
Watford, in their traditional yellow strip, start the game from right to left. Will Hughes tries to get the game off to a flyer with an effort from distance but it sails well over.

PREVIEW
Hello and welcome to tonight's game between Tottenham Hotspur and Watford. With just a handful of games remaining in the Premier League, both teams have something to play for. Spurs currently hold fourth spot in the Premier League but have Chelsea breathing down their necks. Watford, on the other hand, occupy 13th place and could end up in a relegation fight or mid-table safety depending on the results of their last three games. My name is Peter Moloney and I will be guiding you through this one.
