It is more than a new stadium and a new training ground that has signalled West Ham’s moves to embrace the future.

The ability to keep class players and splash out £20million on a striker shows the mentality has changed, manager Slaven Bilic has said.

Speaking at the season launch of the Premier League in London on Wednesday (August 10) Bilic said : “In keeping Dimitri Payet we have shown the club is serious and trying to get to another level, as much or even more than with the new stadium.

“West Ham was always labelled as a club that has to sell its best players, be it Frank Lampard, Rio Ferdinand or whoever. But we have kept Dimi, and we have shown to everyone that the club is thinking seriously.”

While the boardroom are in charge of business, it is Bilic’s job to create a winning mentality and he is confident the team can improve on last season’s seventh-place finish. The London Stadium is a symbol of the change of outlook – and one of the most worrying unknowns.

He said: “We have to adjust. The atmosphere, we can’t compare it with Upton Park but it is good.

“I was a little concerned about it because I know I played and I coached in this type of stadium and sometimes the atmosphere is not ideal. We have played two games there and you can feel the crowd.

“They are not as close as at Upton Park but you can feel them. We are going to try to keep the spectators there with our performances. We are expecting big things.

“It won’t come overnight. The new stadium, the new training ground and new goals - we have to continue to work hard to earn it.”

Meanwhile, Bilic is backing Mark Noble to have another special season – and perhaps win the approval of former Hammers boss and new England supremo Sam Allardyce.

Bilic said: “He’s got everything, he’s at the best age and he’s captain of the club. He had a terrific season with many people - not only me - thinking he deserved to be in the squad; I didn’t see many midfield players have a season like he did last year.

“He has a manger now in Sam Allardyce who knows how good and useful he can be, not only on the pitch but in the dressing room as well.”

“But I have told all the players - like Aaron Cresswell and Andy Carroll - that they have all have a chance but they will not get in the England team because they had a good season last year. They have to play consistently well for West Ham or they are not going to play for England.”
