Eddie Howe singled out hat-trick hero Callum Wilson following Bournemouth's first-ever Premier League victory.
The 23-year-old former non-league striker scored three goals in an entertaining 4-3 victory at West Ham -- who were again reduced to 10 men.
Wilson scored twice before half-time following two errors from Aaron Cresswell to seemingly put the Cherries in control, only for the hosts to hit back early after the break.
Mark Noble was brought down and dusted himself off to slot home the resulting penalty before Cheikhou Kouyate levelled the game seven minutes later.
There was plenty more drama to come as substitute Marc Pugh curled home a well-taken third before Wilson completed his hat-trick from the spot after Carl Jenkinson had been sent off for pulling back the impressive Max Gradel. Modibo Maiga got a home third but Howe's men survived.
There were plenty of good performances for the visitors but Howe was happy to sing the praises of Wilson, who penned a new deal at the Vitality Stadium before the start of their maiden Premier League campaign.
"I don't mind singling Callum out on the back of a hat trick," said Howe. "He was a menace today with his pace. All strikers need goals and it has been a really good afternoon for him.
"The pleasing thing from his perspective is he was clinical. We were dominant, created numerous chances. Pugh's goal is key, a fantastic finish.
"Callum is a huge part of what we are doing. Callum is not going anywhere."
Howe insisted he never doubted his side could go on to win having let a two-goal lead slip and, after opening the season with closely fought defeats to Aston Villa and Liverpool, he was pleased to get an early win under his belt.
"It was bizarre because I didn't think the game had changed, we just gave away some terrible goals," he added.
"But I still felt confident we could get control again. Thankfully the players had the belief. It means everything. you don't want to be waiting too long [for a win].
"It was only two games but I am sure there were doubters out there who thought we were finished."
