West Ham boss David Moyes has pegged tomorrow's Premier League clash with Saints as a 'must-win', when he gave his pre-match address to the media today.
Two points separate Mark Hughes's side and tomorrow's hosts, with the game of huge significance for both clubs, not least because of the fact that Saints' new manager will take charge of his first league fixture.
Alluding to the recent crowd disturbance at the London Stadium, Moyes put emphasis on the role of the fans in supporting his team's efforts to avoid the drop zone.
"I'm hoping we can pick up points from every team," the Hammers boss said. "We look at Southampton and Stoke as must-win games, which they are, but we look at others as ones we can pick up points from too.
"I don't think there's anything between the bottom nine or ten clubs. I think it will go right to the end, to the last week or two of the season.
"We've got to make sure, if we go a goal behind, we come from behind like we did against West Brom. We've got to make sure that we don't let any disruptions affect our minds.
"I think the atmosphere will be great. It has been great, with the exception of one occasion, since I've been here. I've got no worries about the supporters, who I believe are right behind the team."
