He believes that if they don’t have their noses in front after 30 minutes, the atmosphere inside the stadium “will be toxic.”
He told Sky Sports News: “I think this is a 30-minute football match. If West Ham isn’t winning after 30 minutes, I can’t see how they win this with how it is at the stadium, I think it will be toxic.
“West Ham got well beat last time out against Burnley, who aren’t even free-scoring, but won 3-0 and slaughtered them.
“I’m worried for West Ham and the fans are good at reuniting and getting right behind their team, but it’s an ageing side with not a lot of pace so I worry about them.
“For Southampton, I like Mark Hughes and he’s a good manager. He’s one of those that can win six out of nine or lose eight out of eight and I think here, they have to make sure they don’t lose this game.
Like I said, it’s a 30-minute football match and if they’re not losing after half an hour, I can’t see how Southampton don’t get a result.”
