West Ham 1-0 Liverpool
Liverpool have enjoyed over 60% of the possession, but have created very little.

"The game has got very scruffy with some poor passing. If we are looking at Liverpool and wondering if they are anywhere near a title challenge then on this evidence the answer is definitely a 'no'.
"The Can shot that hit the crossbar was the first time we saw any cutting edge from Liverpool.
"They have not threatened West Ham's goal much. If West Ham score the next goal that will be enough. Jurgen Klopp has to go into his dressing room and rattle some of the Liverpool players."

And that is that. Liverpool out of sorts, while West Ham have looked the more dangerous.
Liverpool camped in the West Ham half, pressurising the hosts in these final minutes. Can the Hammers hold on?

West Ham 1-0 Liverpool
And that's the closest the visitors have come to scoring. Good work by Firmino on the right, the Brazilian finds Jordan Ibe and runs into the box to collect his team-mate's low cute cross... the Brazilian then lays off to Emre Can who rattles the crossbar from 20 yards or so.
Lucas swings at fresh air as he attempts a volley outside the box and his comical attempt sparks ironic jeers from the home fans. Liverpool running out of ideas, and time, in this half.
Talking of time, there'll be five additional minutes to this first half.
Once again Liverpool's defence fail to deal with a ball inside the box.
It's a throw in this time which is allowed to bounce at the far post and Aaron Cresswell's shot is deflected by Nathaniel Clyne and requires a low diving save from Simon Mignolet to stop it from creeping in.
Liverpool have had plenty of possession, but have yet to create a truly memorable chance.

"At this moment, it looks flat from Liverpool and if they keep meandering as they are then they will not come away from Upton Park with a win. There is a game to be won for both sides here."
West Ham 1-0 Liverpool
A standing ovation for Manuel Lanzini as he hobbles off. Pedro Obiang is the man who replaces the injured Argentine.
Adrian needs some cotton wool up a nostril after Firmino's boot accidentally makes contact with the Hammers goalkeeper's hooter.
There's another stop in play as Manuel Lanzini is on the turf. It looks as if the Argentine's day is done.

Liverpool, more in hope than belief, ask for a penalty after James Collins clears a Philippe Coutinho shot with the side of his body. But the Welshman did his dirty work outside the box anyway.
The visitors enjoying their brightest spell, monopolising possession and doing so in West Ham's half.

"When Liverpool have got the ball wide, Jordon Ibe can be a handful. But he is up against Aaron Cresswell, the better of West Ham's two full-backs, so they may have more joy if they swapped him to go against James Tomkins at right-back.
"Even though Liverpool have had the ball in the final third as much as West Ham, they look to have more of a cutting edge with Andy Carroll and Michail Antonio.
"I think there will be more goals in this game."

Andy Carroll is a little late on Nathaniel Clyne. An animated Jurgen Klopp demands a foul, rubbing his eyes as he looks towards the fourth official. Nothing is given, though.
Liverpool jittery in defence and, once again, a failure to clear the ball around the box gives West Ham another chance... Enner Valencia, though, slices wide and the visitors are off the hook.
