West Ham vice-chair Karren Brady claimed today that it would be a "corporate crime" to demolish the Olympic Stadium once the 2012 London Games are over.
The Hammers are vying with Tottenham to move into the venue after the Olympics.
The east London club have vowed to keep the athletics track while Spurs plan to rebuild it as a football-only stadium.
An announcement was originally due on 28 January but was postponed because the Olympic Park Legacy Company (OPLC) wanted more time to study the financial viability of the bids.
A decision could now be made this week but the OPLC board currently have no plans to reconvene.
Brady told the BBC: "It's a corporate crime to spend £500million on a stadium and, just four weeks after the Games have finished, bring the bulldozers in. The Olympic Stadium was built on a promise to have a legacy for athletics."
But Tottenham chairman Daniel Levy today hit back and claimed that there had been too much "scaremongering" about Spurs' plans for the stadium.
He added: "Our plans involve the same amount of dismantling and this is in no way a loss of £500m of stadium infrastructure.
"Given how much of the original groundworks, substructure and podium will remain, around £420m worth, we are talking about £80m of above ground infrastructure - all of which will be recycled."
