The pressure has been cranked up on West Ham United boss Graham Potter and he desperately needs a win when Crystal Palace come calling in the Premier League.
The Hammers eased some of the strain on their manager ahead of the international break as a 3-0 win at Nottingham Forest secured their first points of the season.
But Potter's side then slumped to a 3-0 London derby defeat against Tottenham on their return, with Micky van de Ven bringing up a 14/1 bet for us by scoring the killer third.
That has left them in the bottom three after four games of the new campaign and it's hard to see Potter surviving unless their form picks up.
West Ham have already lost heavily at home in two London derbies and they now have another as Palace bid to pile on the pain.
Oliver Glasner was hoping to push on after winning the FA Cup last term but his squad looks weaker after star man Eberechi Eze was sold to Arsenal.
However, the Eagles are still unbeaten in the league, with one win and three draws, so they will head across England's capital in confident mood.
How the bookies view it: No home comfort
With West Ham in such poor form, they are as big as 2/1 for the win at BoyleSports, despite having home advantage. Crystal Palace are 6/4 favourites and the draw pays 9/4.
Recent head to head: Eagles are flying
Crystal Palace have held the upper hand in this fixture of late, losing just one of the last six meetings. Four of those games have been victories, including a 2-0 triumph at London Stadium last season.
Players to watch: Paqueta packing a punch
One of the few positives for West Ham this season has been the fact star man Lucas Paqueta didn't move on in the summer transfer window.
The Brazilian has scored four times for club and country this term and is 7/2 for anytime scorer. He's also 13/8 at Bet365 for a goal or assist.
Palace are relying heavily on Jean-Philippe Mateta at the moment, with back-up striker Eddie Nketiah injured. The giant Frenchman is 6/4 for anytime scorer here with BoyleSports.
Probable line-ups
West Ham should have a healthy squad to pick from, with only the suspended Tomas Soucek likely to miss out. But Palace have a number of injury issues with Chadi Riad, Cheick Doucoure, Nketiah, Caleb Kporha, Ismaila Sarr and Adam Wharton set to all miss out again.
West Ham United: Hermansen, Walker-Peters, Kilman, Diouf, Mavropanos, Summerville, Ward-Prowse, Fernandes, Paqueta, Bowen, Wilson.
Crystal Palace: Henderson, Lacroix, Guehi, Richards, Munoz, Mitchell, Lerma, Kamada, Hughes, Pino, Mateta.
Anything else catch the eye?
Palace have been hard to beat this season but they've found scoring goals a big problem too, with just six across their seven competitive games.
West Ham have also scored just six times in their six games so I'd be surprised if this one was a thriller. Under 2.5 goals only pays 4/5 at BoyleSports but betting against BTTS is better at 21/20.
West Ham's Achilles heel this season has been conceding goals from set-pieces so it could pay to back some Palace players at long odds.
Stopper Marc Guehi is 11/1 for anytime scorer while backing giant striker Mateta to score with a header pays 15/2 at Bet365.
West Ham stopper Max Kilman has conceded two fouls in two of his four Premier League outings this term. He could face a battle with Mateta so over 1.5 Kilman fouls appeals at 11/4 with Bet365.
