West Ham's joy after beating Manchester United last Saturday was short-lived as they slumped to a 1-0 defeat at Brighton & Hove Albion.
Glenn Murray scored the only goal of the game to lift the Seagulls six points clear of the relegation zone going into the Premier League's weekend fixtures.
"We had to work hard and I know West Ham missed a couple of chances, I'm aware of that, but we worked really hard to get the clean sheet," Chris Hughton told the media afterwards.
"They've got really good offensive options coming off the bench and the only way you can keep a clean sheet against them, whey they are in that type of mood, is to defend well and get a little bit of luck. I can see West Ham scoring a lot of goals this season."
Against United, it looked as if things had finally clicked under Manuel Pellegrini, but the trip to the AMEX provided a stark reminder that there is still plenty of work to be done.
Marko Arnautovic, who has been clinical this season, scoring four Premier League goals already, did not have any luck.
The Austrian international had scored in every away game so far in the 2018/19 campaign and he once again found himself in some decent positions.
However, it just wasn't to be - the forward put one chance over the bar from inside the six-yard box. Later, in the dying minutes, he couldn't keep his free-kick on target.
What was Knockaert up to?
It was memorable nonetheless given Brighton's strange tactics. As Arnautovic stepped up, eagle-eyed fans on Twitter spotted Anthony Knockaert kneeling behind the wall:
Philippe Coutinho used to try something similar at Liverpool, just in case the ball went under the wall, though usually to no effect. It's not the first time Knockaert has tried it either.
It's thought Marcelo originally came up with the idea while playing for Brazil against Argentina, fearing Lionel Messi might change it up by dipping in a low free-kick.
