Spurs make their final change as Tanguy Ndombele replaces Harry Winks.

And Watford bring off Daryl Janmaat, who was unable to continue in the end. Kiko Femenia is on.

Another wasted counter-attack chance by Daryl Janmaat as he fails to get a shot in and appeared to hurt himself - although he can continue.

What a game Abdoulaye Doucoure is having for Watford. A rare good Spurs move as Harry Kane tries to pick out Erik Lamela but there is Doucoure to cut it out.

It's not Harry Kane's day. Fellow Harry, Winks, crosses into the Spurs striker. Usually he'd be getting a shot away but he mis-controls and the ball bobbles off Kane's legs.

That is only his 23rd touch of the ball.

Another Watford chance missed. Dele Alli and Harry Winks are both day-dreaming as Abdoulaye Doucoure darts in between them but luckily for the England pair, the Hornets midfielder drags his shot wide.

Spurs make a second change, fairly like for like, as Erik Lamela replaces Lucas Moura.

Watford's finishing this season has been questionable and Gerard Deulofeu cuts inside and shoots wide when he should have done better.

Son Heung-min involved again but Ben Foster is able to catch his cross-shot.

Watford have another chance to double their lead. They've got a four-on-two break and Abdoulaye Doucoure picks out Daryl Janmaat, who can't get a shot in on goal.

Another lucky escape for Spurs.

Son Heung-min has already been Spurs' best player. He's flagged offside as he chases onto a long ball, but at least he's making things happen.

The Premier League has told us that VAR did not consider Watford's rejected penalty appeal as a clear and obvious error - which is why it was not overturned.

A shocking attempt by Spurs goalkeeper Paulo Gazzaniga to clear a back-pass. It loops up into the air but luckily doesn't land for Roberto Pereyra in time.

Spurs striker Harry Kane can't believe it as he's penalised for a sliding tackle on Roberto Pereyra. Probably got the ball but got the man first.

Son Heung-min goes down in the box after a little brush from Craig Cathcart. It was a similar position on the pitch to the first-half Watford claim but there's no way the referee could give that after that earlier decision.

And now Watford should be 2-0 up. Serge Aurier saves Spurs.

Gerard Deulofeu is in on goal but instead of shooting, he squares it to Roberto Pereyra.

Pereyra gets his shot in but Aurier manages to get in the way. Why didn't Deulofeu go alone?

The closest Spurs have come by some way. Half-time substitute Son Heung-min cuts inside and blasts a shot which Ben Foster tips onto the crossbar.

So close.

A good interception by Serge Aurier to stop a Watford attack and start a Spurs one, but in the end Ben Foster gathers.

Only one 'subjective decision' has been changed by VAR this season - a Kurt Zouma goal being disallowed for a foul by Olivier Giroud.

The other decisions changed have been factual ones like offside.

The second half begins with 20 of the players who started the first half.

Spurs make a change at half-time. Son Heung-min is on for Davinson Sanchez. I suspect that's the end of their wing-back system today.
