West Ham manager Sam Allardyce believes the club can become a major force if their bid to move into the Olympic Stadium is successful.
The Hammers will find out next month whether their bid to lease the stadium - which has faced opposition from fellow East Enders Leyton Orient, who fear it could drive them out of business - has been accepted.
Allardyce, who steered the club back to the Premier League via the play-offs last season, said: "Everyone who is a part of West Ham United knows how much it would benefit the club.
"It would take this club to another level if our bid is accepted. It would be a dream come true - and there is nothing I can say more certain than that."
Hammers officials believe the extra revenue the Olympic Stadium would generate on matchdays would allow the club to establish themselves and compete with the game's bigger spenders.
Meanwhile, figures released by the Football League revealed that West Ham topped the list of how much clubs spent on agents' fees last season.
The data revealed that the Upton Park club accounted for almost one-fifth of the £21.7 million spent by clubs across the three divisions during 2011-12.
Championship clubs spent £18.7 million of that - and West Ham shelled out £4.31 million in completing 69 transactions.
Football League chairman Greg Clarke said: "While £21 million is a lot of money leaving the game, it should also be noted that a considerable amount of this total has been spent by a small number of clubs. In fact, almost one-fifth of the overall figure was spent by one club alone."
