Pompey were undone by three goals in seven minutes as they were dumped out of the Carabao Cup by West Ham on the opening day of the season.
The Blues led through Adrian Segecic’s deflected 33rd-minute strike heading towards half-time, only for a late collapse to turn the match on its head.
The Hammers netted twice in the final few minutes of the half, through Valentin Castellanos and Jarrod Bowen, to go in at the break with a 2-1 advantage.
Then, on 50 minutes, Castellanos grabbed his second with a header from Bowen’s cross to seal a 3-1 success for the Hammers.
