Charlie Austin remained hot, scoring his fifth goal in his last four matches to open the scoring, and it only got worse for the home fans at the Olympic Stadium as West Ham slumped to yet another defeat, this time to surging Southampton 3-0 behind goals from Austin, Dusan Tadic, and James Ward-Prowse.
West Ham pressed forward in the early going, seeing a number of touches inside the Southampton box, but the Saints held strong. As the first half progressed, the teams dribbled back and forth through the midfield, with the occasional moment of excessive physicality, keeping referee Jon Moss busy.
Oriol Romeu was cautioned in the ninth minute for a very heavy challenge on Manuel Lanzini near the mid-line.

Southampton began to build themselves into possession past the half-hour mark, and with five minutes to go until the break, West Ham’s leaky defense opened the door again. Ryan Bertrand overlapping on the left cut back to Charlie Austin at the penalty spot and he scuffed a shot past Adrian to put Southampton in front.
Following halftime, the visitors pushed for a second, nearly grabbing it in the 52nd minute when Dusan Tadic’s effort from close range was stopped expertly by a wonderful Adrian save down to his left. That sprung West Ham to life, and the Olympic Stadium responded with a ringing endorsement from the home fans.

Simone Zaza was booked for diving on the hour mark after flopping over a nothing challenge in the box from Romeu. Down the other end, Southampton struck again. With the Hammers dispossessed in their own half, a brilliant flick from Austin sprung Tadic free on goal, and he rounded Adrian and tapped home Southampton’s second.
Down 2-0, Slaven Bilic threw on young Ashley Fletcher and Sofiane Feghouli, both of whom had an impact. The Hammers screamed for a penalty in the 70th minute as Feghouli looked to clean up bright play from Payet, but his shot hit the arm of Bertrand, although from close range it would have been hard for Bertrand to react properly to avoid the contact, and Jon Moss did not award a spot kick.

The home side continued to flood forward past the 75th minute, with Southampton content to sit deep and look to counter. Adrian was needed to keep things from getting worse, as he produced quality saves to keep out both James Ward-Prowse and Pierre-Emile Hojberg in the 86th minute. Ward-Prowse would tack on a third in added time, as a deflection off Angelo Ogbonna opened up the young Englishman to poke home easily.
The three points sent Southampton shooting up the Premier League table, into the top half with nine points after their second straight win. Meanwhile, West Ham remains winless, shut out for the first time this season and owners of the leakiest defense in the league with 16 goals conceded.
