West Ham bounced back well from their midweek mauling by Manchester City, showing character and application in putting a bad result quickly behind them.
The 3-1 win at Southampton's St Mary's Stadium was a perfect response.
Andy Carroll's neat finish came just minutes after Southampton's new signing Manolo Gabbiadini had opened the scoring, with the Hammers defence claiming -- not unreasonably -- an offside decision.
With Pedro Obiang scoring his first goal for the club just before half-time, and Mark Noble claiming a third from a free kick after 53 minutes, this was as comfortable an away win as could be hoped for.
