West Ham United vice-chairman Karren Brady has vowed to consult with the club's supporters over the proposed move to the Olympic Stadium.
The Hammers have been named as the preferred bidder for the ground by the London Legacy Development Corporation, but will only leave Upton Park if its fan are in favour of the switch.
"It is important to understand that while the decision represents a huge step forward, as we have stated throughout, preferred bidder status does not mean that West Ham United have at this stage agreed to the move," said Brady in a statement.
"It remains the case that we will only do so if the final proposal is right for the club and our supporters.
"This includes the necessity of agreeing a Stadium design specification that is acceptable to us in terms of its ability to host world-class football matches."
Brady has set up a meeting with the club's Supporters Advisory Board to gauge feedback on the proposed move, and has vowed to take it on board.
"This is the time for supporters to have their voices heard and a more intensive consultation process will commence immediately," Brady continued.
"This must start by working with our Official Supporter Advisory Board to agree how we take that consultation forward.
"We stand by our commitment to conduct full supporter consultation regarding the move, including the polling of supporters."
West Ham fought off competition from Leyton Orient to emerge as the preferred bidder for the London venue.
