Slaven Bilic saluted a "fantastic" display from West Ham after they bounced back from their midweek mauling to beat Southampton 3-1.
The Hammers were thumped 4-0 at home by Manchester City on Wednesday, and Bilic may have feared the worst when new signing Manolo Gabbiadini fired the Saints ahead after just 12 minutes.
But Andy Carroll equalised within two minutes, Pedro Obiang added the second before half-time and a Mark Noble free kick, deflected in by Steven Davis, lifted West Ham back into the top half of the Premier League.
"After the City game I said that no matter how much that hurt us it should not affect our confidence,'' Bilic said.
