First change at Old Trafford.

Daryl Janmaat runs off the pitch and straight down the tunnel to be replaced by Kiko Femenía - a like-for-like sub.

Is Janmaat injured?

David Freedman: United need an insurance goal. Watford will score.

Ashley Scott: United will be punished for all that sloppy play beginning of the 2nd half

As I said, Huddersfield would be down now if they lose and Burnley and Southampton both hold on to win and Wilfried Zaha goes close to the opener but his shot is well blocked.

The goal doesn't surprise me because Nathan Redmond is having a lot of the ball.

He's picked the right choice, it's a great finish from Pierre-Emile Hojbjerg.

Watford are really giving this a good go - they're attacking and playing some decent football.

After Daryl Janmaat slices a decent chance over the bar, Roberto Pereyra forces a one-handed save from David de Gea.

There's plenty of life left in the Hornets.

Evidence of a Wolves fightback at Turf Moor.

A powerful run by Adama Traore ends in Diogo Jota bending a shot just wide.

Then Ivan Cavaleiro blazes over when he should have done better.

Has Nuno Espírito Santo read the riot act at half-time?

Would have been some goal! Wilfried Zaha spins away from two defenders tight on the touchline, tees up Patrick van Aanholt and his curler is heading into the far corner until Ben Hamer moves across to make the save!

Bright and breezy start to the second half by Watford.

Another decent move ends with Gerard Deulofeu testing David de Gea.

It's an easy save in the end but the Hornets have come flying out of the traps.

What happened there?! A collective lack of concentration as Palace play the ball forwards, everyone stops waiting for an offside flag but Wilfried Zaha is waved on.

He has so much time and space - too much, it transpires, as he rather panics and puts in a poor cross which is easily cleared.

Zaha then punts the ball clean out of play. Playing with the weight of the world on his shoulders?

Away we go in the second halves...

A half-time change for the hosts - Max Meyer has been hooked with James McArthur on in his place.

The race for 'best of the rest' is hotting up.

Just two points currently separate Wolves, Leicester, Watford and West Ham in the race to finish seventh.

A smattering of boos at Selhurst Park at the break. Huddersfield's Premier League future in immediate threat today, but Crystal Palace look far more nervy. Perhaps the shackles are off for Siewert's team already?

You still feel though if Palace could activate their obvious attacking threats, they'd find a way through here.

Iain Moss: Mata has been absolutely central to Manchester United turning this game round. Martial & Matic have been passengers. Martial's reading of the game is awful!!

Richard Browne: This United team plays like Leicester’s PL winning side. Comprehensively outplayed but winning.

Comprehensively? A bit harsh that, Richard.

FA Cup on Wolves' mind?

For 25 minutes, Watford were outstanding. That energy, pressing and creating chances - if you don't score goals, that will fade away later on.

Warm applause rings out at Old Trafford but Watford are far from done.
