West Ham United co-owner David Sullivan has said that he is worried about their capacity to fill the Olympic stadium. West Ham are already in a battle against the drop and, with their move to Stratford still three years away, the Irons had to prove their Olympic project is sustainable.

Sullivan told The People: “We’ve had to convince accountants that we can survive forever in the Championship. But I still think we can get 40,000 attendances in that league.”

Hammers also plan to cover the athletics track with synthetic turf – introducing temporary seating behind the goals.
