That's defender and auxiliary goalkeeper, Cedric Kipre.

Great block by Cedric Kipre to deny Ollie Cooper a second goal.

Brilliant save from Ryan Allsop!

That's a superb stop to deny Ben Cabango as he tips his effort over the bar.

Watford are in total control of this game now, that third goal has really taken the sting out of Luton.

Keinan Davis, whose third-minute goal set the home side on their way, has been exceptional today, but he has gone off injured to be replaced by Vakoun Bayo in the only negative so far for the Hornets.

Jordan Clark has a snap shot from distance which is comfortably saved by Daniel Bachmann in the Watford goal. The home side are cruising.

No team had ever won two south Wales derbies in a row in 110-years.

Now Swansea are going to win three, by a margin of 3-0, 4-0 and who knows.

The times they are a changing.

Shane O'Neil: Why is it Luton only turn up against teams in the top eight? As soon as they play anyone low down the table, they're rubbish. Promotion won't happen while this continues.

There's the second goal, I'm not going to say game over now but it's close to it.

Editor's note: I've already said it. :)

That's what they are playing for Cardiff, a little bit of hope in situations like that, sending men forward and who knows, it could happen for them.

A rare moment for Cardiff as Callum O'Dowda crosses and Mark Harris heads at goal, but his effort is over the crossbar.

I'm not sure what Michael Obafemi was doing there, that is one of the situations that could level this game back up, Swansea City going down to ten men.

Another flash point as players come together after a freekick.

Joe Ralls is booked.

The second half has been like Fight Club.

Despite the first rule of Fight Club, I will continue to report on the game.

Michael Obafemi booked for dissent.

Swansea picking up silly yellow cards when they have a man advantage is, well, silly.

A powerful shot from Michael Obafemi after a neat turn just outside the penalty area, but the effort is straight at Steven Benda.

Minor flash point as Alfie Doughty takes out Watford's Ken Sema, with Doughty booked.

A Luton corner then goes all the way through the Watford penalty box and substitute Gabe Osho can't turn it in at the far post.

The away side have started the second half much bettter.

Wrong captions only.

Harry Darling and Callum O'Dowda clash after a meaty challenge from Darling on the Cardiff man.

Darling then gives O'Dowda some trash talk, O'Dowda reacts and both players are booked.

The kind of nonsense players only do in this game. Tempers flare.

It's really important Cardiff keep it at one. If it goes to two then I don't think there's any way back for them.

The only danger for Swansea is complacency.

The home side get things going in the second half.

Luton manager Nathan Jones has made a change at half-time, with Gabe Osho replacing Sonny Bradley.
