The Olympic Stadium may not be ready for use again until 2016 according to Dennis Hone, the man in charge of overseeing the transformation of the £468m arena for its post-Games future.
If West Ham United's bid, which remains the clear favourite of the four, is accepted, the club may not move in until the 2016-17 season. The stadium, which will be reduced in capacity to 60,000, is due to host the World Athletics Championships in 2017.
Negotiations are ongoing, with who will foot the £200m bill for making the arena suitable for football believed to be the main sticking point.
