West Ham should be forced to leave the London Stadium if they are relegated from the Premier League this season.That’s the view of talkSPORT’s Jamie O’Hara, who believes the struggling Hammers are not going to survive the drop.West Ham lost their third-straight Premier League game on SaturdayGettyNuno Espirito Santo‘s side were beaten 1-0 at home to Fulham on Saturday, with Raul Jimenez heading in a late winner.It was their third straight defeat and extended their winless run in the top flight to seven games, with their last victory coming at the start of November against Burnley.West Ham still sit 18th in the Premier League and five points from safety, as relegation looms if their form can’t be turned around.And ex-Tottenham midfielder O’Hara can’t believe the situation the Hammers are in, saying on The Sports Bar on Saturday night: “What is going on at West Ham? They are terrible.”Co-host Jermaine Pennant then pointed out: “They are potentially playing at the London Stadium in the Championship, the biggest stadium in the Championship ever.”The largest capacity ground in the second tier is currently Sheffield Wednesday‘s Hillsborough, with 39,589 seats. West Ham’s London Stadium, which was originally built for the 2012 Olympics and cost around £750m, can hold 62,500 fans.On the stadium, an exasperated O’Hara replied: “I think if they go down, they shouldn’t be allowed that ground. “They would have to vacate, share with Leyton Orient or something.“It’s unacceptable to have the Olympic Stadium in the Championship. It’s unacceptable.O’Hara believes West Ham should have to leave their stadium if they go downTalkSPORTThe London Stadium would hold 30,000 more people than the current highest-capacity Championship groundGetty“This thing is used to watching winners, gold medallists, and they’re going to have Championship football.“It’s unacceptable. They should vacate.”‘Toxic’ atmosphere leading to dropO’Hara and Pennant went on to discuss how West Ham are going to stay up this season when their home form is so poor. The Hammers have lost seven and won just two of their games at the London Stadium this season – and that is a worry. “West Ham have absolutely fallen apart. I’m not convinced [they can get out of it], I think they’re gone,” O’Hara said.Pennant added: “You’ve just got to look at the teams around them. Nottingham Forest, they’re going to be sturdy. Their home advantage will keep them in the league. Leeds too.”The forlorn Hammers are in major danger of relegation this seasonGettyThey are sitting five points from safety after 18 games“Leeds, Elland Road can be a fortress if they get it right,” O’Hara joined in. “Sunderland have been superb.“The problem West Ham have got is at home, it’s so toxic, the atmosphere is so bad and the fans have had enough of the football they’re watching, had enough of the owners.“So when they’re turning up, the atmosphere is all wrong, plus the stands are miles away from the pitch…but they can’t change that, there’s nothing you can do.“I’m just looking at it going, they are done. Gone. This is the season West Ham go down.”Not losing hope Despite West Ham facing a tough relegation battle, manager Espirito Santo remains hopeful that his squad can find form.Speaking after defeat to Fulham, he said: “We all make mistakes.Espirito Santo is remaining confident despite his side’s tough situationGetty“It’s not about individuals. It’s about how can we react as a team when we have an important game in two days.”He added: “We cannot hide from the situation that we are in, but I’m positive that things are going to turn around.”The Hammers take on Brighton back at the London Stadium on Tuesday, December 30 at 7:30pm.Coverage of the game will be available exclusively on the talkSPORT app, with commentary coming from Rob Dugmore.To tune in to talkSPORT or talkSPORT 2 through the website, click HERE for the live stream.
