Former Coventry City CEO Paul Fletcher has said that the London Stadium should be knocked down and rebuilt.
Mr Fletcher, who is involved in stadium development, told the BBC about West Ham's ground which is the stadium that was used in the 2012 Olympics: "Either we go on as we are for the next 30 or 40 years or we knock it down and start again.
"Something has to give. If you want to satisfy spectators the only way to get those spectators near that pitch is to knock it down and start again.
"I said what you must do is design a football stadium that converts to an athletics stadium for two weeks of its lifetime.
"When I build my football stadiums, my number one concern is the spectator.
"What they've done is tried to convert an athletics stadium into a football pitch and, in my opinion, it doesn't work.
"The building was almost built when they started to talk to West Ham.behind closed doors until the issues are solved.
"Let's face it, there was only going to be one end user and it was only going to be West Ham.
"Everyone in those days spoke about legacy. The only legacy was going to be as a football stadium and they should have been talking to West Ham and ask them what they want."
