West Ham vice-chairman Karren Brady is confident the Hammers will be able to fill their new ground after being confirmed as the anchor tenants for the Olympic Stadium.
The Hammers are set to move into the 54,000-seater stadium in 2016.
"Will it be world class? The answer to that is yes. It is going to be a UEFA 4 category, which is the highest level of stadium you can have," she told Sky Sports News.
"Will it have retractable seats bringing the action and the supporters really close together? The answer to that is yes.
"Will it look like West Ham? Will it feel like West Ham? Well, West Ham have supremacy for all their fixtures. The answer to that is yes.
"And I can exclusively tell you that we have already agreed that we can name two stands the Bobby Moore Stand and the Sir Trevor Brooking Stand."
The capacity of West Ham's new home will be significantly greater than Upton Park's 35,000, but Brady is convinced they can pack out the stadium.
She said: "13 of our last matches have been sell-outs, which shows that we do need a bigger ground.
"I think there are a lot of supporters who are interested in seeing what the Olympic Stadium looks like, from home and away."
