David Moyes admitted his second spell at West Ham could not have got off to a better start after a thumping 4-0 win over Bournemouth.
Mark Noble scored twice while Sebastien Haller and Felipe Anderson were also on target as the Hammers stopped the rot that had set in under previous manager Manuel Pellegrini.
Moyes received a lukewarm reception from the home fans before kick-off, but those underwhelmed by his appointment were not complaining by the end. He said: "I don't think I could have had a better start. But I can't take the credit, the players take the credit with their attitude and commitment, it felt as if they could give the supporters something. They played really well.
"We've only had a couple of days with them and I tried to make it as simple as I could. In truth, I don't know most of the players but I tried to use every bit of time, I had a conversation with them all.
"Ultimately we tried to work on a good defensive shape and making sure we didn't lose possession.
"It's the first game and felt I didn't have enough time to work with the players. That's why it's difficult to take any credit.
"It was about being brave on the ball, trying to regain confidence, trying to regain the trust from the crowd."
West Ham took a 17th-minute lead when Noble's shot deflected off Lewis Cook and wrongfooted Cherries keeper Aaron Ramsdale.
Nine minutes later West Ham doubled their lead when record signing Sebastien Haller acrobatically volleyed in a Ryan Fredericks cross. Noble tucked in the third from the penalty spot after he was fouled by Harry Wilson before half-time. Then Anderson grabbed a breakaway fourth after the interval to finally get off the mark for the season.
Moyes added:"All I'd said to him was 'give us a Brazilian goal'. And to be fair to him, he did."
Everything was going West Ham's way, so much so that Aaron Cresswell even had a red card for a foul on Ryan Fraser downgraded to a yellow by VAR.
While the Hammers levered themselves back out of the bottom three, injury-ravaged Bournemouth have slid into it.
