With Andy Carroll serving a three-match ban, his strike partner, Kevin Nolan, took the opportunity to shine on Saturday, helping West Ham to their fourth successive Premier League victory.
After Southampton took the lead, Nolan set up Matt Jarvis's equaliser with a superb long pass before putting the game out of the Saints' reach in the 71st minute with his sixth goal in nine games.
After the game, West Ham manager Sam Allardyce praised Nolan for the manner in which he has bounced back from recent disciplinary troubles, Ian Stokes of The Daily Mail:
His contribution has been massive, not just his goals. The pass he made for our equaliser split a very resilient Southampton defence open.
He had a lot of time to reflect on what happened. It was about rolling his sleeves up and using those weeks to define himself and show everyone what he can really do.
Thanks to Nolan's efforts, the Hammers now find themselves seven points clear of the relegation zone.
