And he does. 

Dwight Gayle comes on in place of the battered and bruised Yohan Cabaye.

Yohan Cabaye is still trying to run off a heavy challenge from Claudio Yacob. The Palace man looks quite uncomfortable.

But the ball has fallen to him in the box...and he completely skews it over the bar.

And then the poor lad is stung again by a tackle from James Chester, who receives a yellow card for a high foot.

Perhaps time for him to come off...

West Brom bring on the heavily tattooed James McClean for Stephane Sessegnon, who's been excellent for the hosts in attack.

Palace goalkeeper Wayne Hennessey is sent into action as he dives to his right to gather Stephane Sessegnon's low 20-yard drive.

Palace go on the attack now and they have a big penalty shout!

Darren Fletcher looks like he's bundled over Yannick Bolasie...but the referee is having none of it.

A real in-swinger of a ball from West Brom sub James Chester causes some trouble in the Palace box before being cleared for a corner.

Craig Gardner takes it, but Palace win back possession.

West Brom have got their passing rhythm back again, but a long ball over the top to striker Saido Berahino is cleared by the Palace defence. 

Now it's the visitors' turn to press.

Yannick Bolasie tries to barge through on the left wing but he loses the ball out of play.

Jay: 18 more goals and West Brom can go above Everton.

Andy Walton: Memo to West Brom - it's a game of 90 mins not 45. 

West Brom earn a free-kick from near the corner flag on the right-hand side.

It's played in by Craig Gardner but is collected by goalkeeper Wayne Hennessey.

Palace's Yohan Cabaye then goes in the book after he clips Claudio Yacob from behind.

We're back to playing it around nicely in midfield again which, to be honest, I'm grateful for for a couple of minutes.

But wait...West Brom are on the attack again. Saido Berahino tries to bend the ball across the penalty box from the right but to no avail.

Craig Dawson then attempts a cross from a similar area but it's cleared again by Palace.

It's now Palace's turn to go on the attack...and they earn a corner.  

Jordon Mutch punts the ball into the box and West Brom goalkeeper Ben Foster comes rushing out with speed and power to clear the danger. Quite a brave move, that. 

Salomon Rondon marches forward once again and West Brom are hungry for another goal.

Craig Gardner is fed out wide on the right and he tries to find a team-mate in the box, but it's cleared by Palace for a corner, which comes to nothing.

So much drama at the Hawthorns.

Scott Dann screams for a penalty after being pushed by West Brom's Gareth McAuley. The referee plays on

And now Saido Berahino has a go at the other end. He runs and runs and eventually swerves a beautiful effort which hits the crossbar.

I'm breathless.

Yannick Bolasie whips a ball in from the left and it eventually finds Wilfried Zaha on the right.

But the Palace man is dispossessed and West Brom go on the attack.

Salomon Rondon performs a couple of step-overs into  but he couldn't quite find Saido Berahino.

We're back under way at The Hawthorns.

Yannick Bolasie has indeed entered the fray, in place of the rather disappointing Emmanuel Adebayor. 

It looks like Bolasie and Wilfried Zaha will go out wide, with Connor Wickham down the middle. 

Yannick Bolasie is warming up on the pitch at half-time and it looks like he's going to come on.

The former Bristol City winger returned to action as a substitute last weekend, in the FA Cup win over Tottenham, following a hip injury.

Could he be the man to inject some much-needed vitality into the Palace team?

Crystal Palace actually edged possession in the first half, believe it or not....

Dan Bell: This is why Newcastle fans wanted rid of Alan Pardew. He isn't as good as you all think.

Alex Johnson: 3-0 up and there is hardly an atmosphere. What are you paying for?
