Dominic Solanke’s late equaliser denied West Ham an opening-day win as Bournemouth hit back for a 1-1 draw.
Jarrod Bowen had fired the Hammers into the lead early in the second half with a spectacular curler from the edge of the box.
But Bournemouth, playing under new boss Andoni Iraola for the first time, were good value for the point they earned when Solanke rounded Alphonse Areola with eight minutes remaining.
It has been a troubled summer for West Ham following their Europa Conference League success last season with the departure of Declan Rice, Manchester City’s attempt to lure Lucas Paqueta away and a lack of new signings coming through the doors at the London Stadium.
They arrived on the south coast with essentially last season’s team, minus Rice, and not much in the way of optimism.
Yet they almost went ahead early on when Said Benrahma fed Tomas Soucek, whose effort bounced back off the inside of the far post and into the grateful arms of Bournemouth keeper Neto.
The Cherries were relieved again when Michail Antonio’s flick from a corner was cleared from underneath the crossbar by Philip Billing.
But Bournemouth had their chances too as the first half wore on, with Solanke slipping in David Brooks who fired just wide.
Solanke then chased a long ball over the top only to be denied by the long leg of Hammers defender Kurt Zouma, before Areola beat away another Brooks drive.
The second half almost began with a bang for Bournemouth with Brooks letting fly on the volley from 20 yards, forcing Areola into an acrobatic save.
But it was the Hammers who broke the deadlock moments later after Pablo Fornals, trying to fill a Rice-shaped hole in the West Ham midfield, won possession 30 yards out.
Bowen’s last kick of the previous campaign was the late goal which secured the Europa Conference League trophy against Fiorentina 66 days ago.
This time he collected the ball off Soucek 20 yards out, cut onto his left foot and buried a superb, curling effort beyond the dive of Neto.
Bournemouth, playing their new brand of easy-on-the-eye, expansive football, tried to hit back and Areola saved from Solanke before Joe Rothwell’s shot clipped the crossbar.
Their dominance told in the 82nd minute when Antoine Semenyo’s wayward shot fell at the feet of Solanke, who showed tremendous composure to slip round Areola and tap into an empty net.
