Yannick Bolasie floats a shot from range onto the roof of the net.

FIVE MINUTES added on. Hope springs for Watford...

Watford just look frustrated as nothing they try comes off. Looks like a home defeat.

“If we see the game out with all 22 players on the pitch I’ll be surprised the way it’s going. All these yellow cards seem to have come in the second half.”

Will we see #pardewforengland trending? It would make life more interesting on the international front I reckon. Into the final stages. Can Palace hang on?

Is it going to be another away win for Palace?

Scott Wilcox: In tournament football, every game is away from home. Just saying. #pardewforengland, external

Might be getting carried away slightly.....

That's initially rubbish from Dwight Gayle as he runs into a cul-de-sac after beating the offside trap, it's then genius as he somehow extricates himself into space and powers in a left-footed drive that flashes a yard wide of the post.

His reward is to be hooked. On comes Frazier Campbell. 

Yes, yeh, yeh. You should see the weather in Salford.

Eight minutes left. The neutrals don't need any added time.

Jason Puncheon curls a free-kick over the wall but straight at Heurelho Gomes in the Watford goal. Puncheon is then booked for a hack at Ben Watson as the away end proclaim him as 'one of their own.'

“A little bit more defensive thinking from Alan Pardew, still looking to defend a little deeper. McArthur’s also bigger for set pieces, so it makes sense. Cabaye has done his bit.”

Almost the game-sealer. A cross from the left is headed down by Wilfried Zaha and Dwight Gayle gets across his man to nudge a volley on goal - but he can only find the side-netting.

Incredibly bad free-kick from Watford sub Steve Berghuis lets Palace off the hook. Palace withdraw the now booked Yohan Cabaye and on comes James McArthur. Will there be a siege from the home side?

Matthew Bennett: Annoying goal to concede. It's the only way Palace can ever score against Watford though.

Kumailj: Zaha winning the penalty against Watford? Déjà vu

BBC Sport's resident Watford guru tells me that Wilfried Zaha was the Palace player fouled by Marco Cassetti for the decisive penalty in the 2013 play-off final. Basically the same place too.

Watford didn't learn their lesson. Yohan Cabaye is booked this time. Definitely.

'It's just like Wembley again' sing the away fans as Palace enjoy their lead. Just over 15 minutes left as Watford chuck on Nathan Ake. 

Allan Nyom is the man off.

“To be fair it’s been coming. Nyom is reckless and he’s keen, but in the box that’s going to cause a problem.

"Very, very cool penalty right in the top corner from Cabaye, Gomes is getting nowhere near that one - and I'm hoping that will get this game going."

Watford instantly have a sight of goal but Idion Ighalo is blocked out. The Hornets have to push on now which may allow Palace more joy on the break.
