It's been all Palace since Watford's goal and the noise levels have gone up to 11 - which we all know is one louder - but Pape Souare's long-range effort is the latest to frustrate the home fans, going straight at a yellow shirt and then away to safety.

Heurelho Gomes drops down to his left to tip a Yohan Cabaye effort from 20 yards put around his right hand post.

Palace's Scott Dann concedes a corner, sliding in to thwart a lovely touch from Nathan Ake. 

Brave stuff from Watford's Nathan Ake, who throws his head in towards a Palace boot with no regard for his own safety. At the other end, Yohan Cabaye tries an ambitious shot from 30 yards but he hooks it high and wide with the kind of up-and-under you'd see in rugby.

There's been no goalmouth action as yet at Selhurst Park, no pattern either but there's time for an improvement.

That's nearly more like it for Emmanuel Adebayor, he's flagged for offside when trying to latch on to a ball over the top from deep but that's a possible out ball for the hosts today, especially as he skilfully brought it down without knowing he was offside.

Watford enjoy a spell of pressure for the first time without threatening Wayne Hennessey. Palace in response try to bring Emmanuel Adebayor into the game, but it's not happened yet for the much-travelled striker.

Palace get the first corner, but Yohan Cabaye commits the heinous crime of not getting the ball over the first man allowing Watford to clear.

Early business sees neither side imposing themselves, with Connor Wickham horribly overhitting a cross to no-one in particular.

And after some genuine-looking affection between the two managers, we're off!

Referee Robert Madley leads the teams out to the strains of the Dave Clark Five's peerless  "Glad all over". Troy Deeney is Watford's skipper, while "the pride of south London" (as the PA man says) are fronted by the impressively bearded Mile Jedinak.

The teams have headed for the warmth and comfort of the dressing rooms for the final instructions from Messrs Pardew and Sanchez Flores.

Match of the Day commentator

"This fixture is a real opportunity for one of these clubs to get back on track. Between them they have only managed one win in the last eight games.

"When Alan Pardew said last week's point at Swansea felt like a win, it was an indication of how relieved he was to halt their slide. He'll now be hoping with home advantage they can get back to winning ways.

"Having faced Chelsea and Spurs in quick succession, Watford may relish this capital meeting a little more.

"Their defeat at White Hart Lane when Troy Deeney came off the bench was a reminder of how important their captain's influence is. He'll look to ensure his team are still above Palace in the table."

Crystal Palace were fifth in the table - two points off the top four - when they drew at Bournemouth on Boxing Day. A poor start to 2016 means they started today 12th in the table, 15 points off the top four.
