Cherries 'must be more ruthless'
Simon Brotherton
MOTD commentator at Upton Park
Bournemouth will hope to get on the board at the third time of asking after two narrow defeats in which they've played well and looked comfortable but ended up empty handed.
They won't get as many chances this season in the Premier League as they had last year in the Championship so must be more ruthless when they do arrive.
Slaven Bilic will look for a more assertive showing from West Ham after upsetting Arsenal only to then fail to cope with Leicester last week when the onus was more on them as the home team.
The 0-0 is my prediction by the way - my predictions are like my attitude to life; constantly prepare for disappointment and if something good happens it's a nice surprise.

I hope Bournemouth do not also emulate Burnley's habit of playing well but being beaten and then getting a little pat on the back afterwards before being sent on their way. They do not want that.
I liked the way they played against Liverpool they did not carry much of a goal threat from open play and, as badly as they need to get a positive result at Upton Park, I cannot see it happening.
It will not be straightforward for West Ham, though.
Team news
West Ham start with Darren Randolph in goal following Adrian's suspension. Their other change sees Kevin Nolan come in for 16-year-old Reece Oxford, who has picked up a knock.
Bournemouth's starting line-up are unchanged from the side who lost 1-0 to Liverpool, although Yann Kermorgant is added to the bench. £8m summer signing Tyrone Mings remains a substitute.

If Slaven Bilic was willing to make such an early change, Aaron Cresswell was perhaps lucky there doesn't appear to be a senior left-back on the bench.
Charlie Daniels drags a shot from distance wide as Bournemouth continue to dominate.
SUBSTITUTION
West Ham bring off Angelo Ogbonna for James Tomkins in defence - some fans are booing that. The Italy international didn't look injured and he's not getting treatment on the bench.

This is Bournemouth's second goal. Note Aaron Cresswell playing in Callum Wilson.

Aaron Cresswell has another nightmare as Callum Wilson takes the ball off him but Darren Randolph stops his cross with his feet.
Bournemouth aren't done yet though and Simon Francis crosses to Josh King who blazes over from six yards out.
West Ham are awful at the moment. Bournemouth could seal this by half-time.
Post update
Callum Wilson has a chance for a hat-trick, the man is on top form at the moment. He plays a one-two, gets the ball out wide right and fires into the side-netting.
There had been quite a bit of talk in the summer than he could have a really big season. They might just have been right.
GOAL - West Ham 0-2 Bournemouth
Callum Wilson
It's a second for Callum Wilson. Aaron Cresswell, who was more at fault for the first goal than I'd initially realised, does even worse here.
It's a horror moment for the Hammers left-back as he passes the ball back and it's intercepted by Wilson to fire home from eight yards out.

West Ham defender Carl Jenkinson has to clear a cross by Matt Ritchie although he initially miscontrols it before getting it sort of clear.
Ritchie has another pop at a cross but this one goes wide.

We are back under way now and Bournemouth are on the front foot.

A drinks break! They are having a drinks break! In England! Because of the heat! I've seen it all now.

West Ham have been pushing for an equaliser but they don't look like the exciting capable side who beat Arsenal 2-0 on the opening day.
They look more like the side who lost 2-1 to Leicester last weekend.
Post update
Josh King is racing onto a long ball for Bournemouth but West Ham keeper Darren Randolph flies out of his goal and punts it about 70 yards into the corner like a rugby player aiming for touch.

Bournemouth captain Steve Cook miskicks as he attempts to punt a long ball forward out for a corner but just before Dimitri Payet can pounce, the Cherries man does get a foot to it.
The corner ends up with Cheikhou Kouyate heading it over.

Final Score
"Great finish from Callum Wilson. Sometimes when you come up to the Premier League, it's about the players you keep as well as the ones you sign and in keeping Callum Wilson, for me that could be the difference between going down and staying up."

This season we can show you how goals were scored using Opta graphics. Bournemouth's opener was pretty straightforward really. Wing play, cross, goal.
Post update
West Ham's summer signing Dimitri Payet - a fantastic talent - slides a brilliant ball through to Cheikhou Kouyate but keeper Artur Boruc comes flying off his line to smother it.

All West Ham have to do is clear their heads of disappointment and self-doubt and to get back playing. They all have a job to do.
Post update
That's the 13th goal Darren Randolph has conceded to Bournemouth in the past year, although he could have done little about that.
GOAL - West Ham 0-1 Bournemouth
Callum Wilson
Bournemouth's first ever top-flight goal.
Full-back Simon Francis charges down the right, shrugs off Aaron Cresswell perhaps a bit too easily, and crosses to Callum Wilson, who fires home first time with power.

Slaven Bilic tested West Ham midfielder Reece Oxford to see if he was ready and he is. But it's important not to push him too much.
DISALLOWED WEST HAM GOAL
West Ham defender Winston Reid heads home the corner but he'd shoved Tommy Elphick to do it and it's disallowed.
Post update
A corner to West Ham as the Hammers break, with Dimitri Payet influential in it, and Bournemouth just about clear with Kevin Nolan ready to shoot.

Bournemouth keeper Artur Boruc gets his first touch as he holds onto a cross aimed at Kevin Nolan.
West Ham break and they have a corner.
Post update
Bournemouth start the half attacking but it comes to nothing. About half of this pitch is really shady, I hope not to much happens there or else I'll strain my eyes.
KICK-OFF
As we get under way at Upton Park, a reminder of the line-ups.
Post update
It's hot by all accounts in east London. Not so much in this office in the north of England I'm sat in.
Post update
Handshakes time at Upton Park. Hammers fans sing a song about bubbles as they like to do.
Almost time to go.
'Not you again'
Republic of Ireland keeper Darren Randolph makes his Premier League debut for West Ham today. Suspended first-choice Adrian misses his first league match since New Year's Day 2014, ending a run of 58 consecutive appearances.

Cherries 'must be more ruthless'
Simon Brotherton
MOTD commentator at Upton Park
Bournemouth will hope to get on the board at the third time of asking after two narrow defeats in which they've played well and looked comfortable but ended up empty handed.
They won't get as many chances this season in the Premier League as they had last year in the Championship so must be more ruthless when they do arrive.
Slaven Bilic will look for a more assertive showing from West Ham after upsetting Arsenal only to then fail to cope with Leicester last week when the onus was more on them as the home team.

I hope Bournemouth do not also emulate Burnley's habit of playing well but being beaten and then getting a little pat on the back afterwards before being sent on their way. They do not want that.
I liked the way they played against Liverpool they did not carry much of a goal threat from open play and, as badly as they need to get a positive result at Upton Park, I cannot see it happening.
It will not be straightforward for West Ham, though.
Team news
West Ham start with Darren Randolph in goal following Adrian's suspension. Their other change sees Kevin Nolan come in for 16-year-old Reece Oxford, who has picked up a knock.

West Ham: Randolph, Jenkinson, Reid, Ogbonna, Cresswell, Obiang, Noble, Kouyate, Nolan, Payet, Sakho. Subs: Spiegel, Tomkins, Jarvis, Collins, Maiga, Lanzini, Cullen.
Bournemouth: Boruc, Francis, Cook, Elphick, Surman, Gradel, Daniels, Wilson, King, Ritchie, O'Kane. Subs: Federici, Gosling, Pugh, Mings, Smith, Kermorgant, Distin
West Ham v Bournemouth (15:00 BST)
Bournemouth came into the season on the back of a 13-match unbeaten run that took them to the Championship title.
But they're in the big time now and life isn't as easy. They didn't play badly against Aston Villa or Liverpool but lost both matches 1-0.
How will they get on against Jekyll-and-Hyde West Ham? Fantastic against Arsenal on the opening day, not so good against Leicester.
Let's find out.
