The man behind Birmingham's proposed super-stadium project has pledged that the £340 million scheme would leave Wembley in the shade.
Las Vegas Sands executive Rodney Brody - the entertainment boss who first approached Birmingham City over the sports-casino scheme - said the City of Birmingham Stadium would dwarf the new Wembley.
"Who is Wembley bringing benefits to? Wembley is bringing benefits to the FA. Who else is Wembley benefiting?
"Wembley will be the greatest football stadium in the world. But this will be the only multi-sports and entertainment stadium in Europe.
"This will be the only site of its kind in Europe. There will be four to five million extra visitors coming to Birmingham, which will be tremendous for business and the country.
"This will give Birmingham a fantastic stadium for which they have been crying out for years. This is a once in a lifetime opportunity. It's a million miles away from what you can imagine in this country."
Mr Brody, the head of development UK and Europe for Birmingham City's partners Las Vegas Sands, said the key to the success of the project - underpinned by a huge casino - was a regeneration scheme saving Birmingham City Council £55 million.
"Wheels Park is an area of nearly 60 acres. It has fallen into disuse and is contaminated. Just to make it usable would cost up to £55 million. The only people who are going to win here are those who scream regeneration."
