The numbers behind 2018
England will promise to deliver Fifa the most profitable World Cup in their history when they present their bid to stage the 2018 tournament on Friday.
The pledge is one of the key messages contained in the 1,752-page bid book which will be presented to the Fifa president Sepp Blatter by former England captain David Beckham.
I am with England 2018 chief executive Andy Anson and other members of the bid team as the book makes its way to Fifa headquarters in Zurich on flight BA 714.
As we took off from Heathrow on a specially branded jet complete with a nose cone painted as a football, Anson told me the English game's commercial success would be one of the strongest arguments for bringing the World Cup back to England for the first time since 1966.
"The English football market is the most successful in the world and we are sure we will generate more money for Fifa than South Africa this summer and Brazil in 2014," said Anson.
What does that mean in numbers?
As I wrote in my blog from Johannesburg earlier this week, South Africa 2010 will already break all previous records, netting Fifa £2.1bn in TV and sponsorship alone.
But England 2018 estimates they can increase that income by a third, taking it to near the £3bn mark.
On top of that, Anson revealed they expect to make more than £600m from the sale of tickets during the tournament. That money goes to the host country rather than Fifa, which means the World Cup could even make a profit for the English organisers.
Jerome Valcke, the general secretary of Fifa, has made it clear to all bidders that the world game's governing body does not want countries putting their finances under pressure as governments feel the squeeze following the economic downturn.
Jeremy Hunt, the new secretary of state for Culture, Media, Sport and the Olympics, signalled on BBC's Newsnight on Wednesday that no part of his department would be immune to cuts.
But the World Cup bid should be immune from any fallout here for two reasons:
1. The only public commitment from the former Labour government was a £2.5m loan.
2. If England's bid is successful, then the government has agreed to provide guarantees worth £300m while each of the 12 host cities included in the bid have underwritten guarantees worth £400m.
England's bid team will also argue that the government (whatever combination of colours it is by 2018) will not have to spend money developing new stadiums as only four new grounds - Tottenham, Liverpool, Bristol and Nottingham - are included in the long list of 17. Each of those new stadiums are being developed with limited public money.
The commitment of David Cameron's new coalition government to sport will be interesting to assess in the coming weeks.
Cameron is known to be on side with the bid (his media adviser and former News of the World editor Andy Coulson is a keen Spurs fan and close to members of the 2018 team) while the Conservatives were making it clear, in the run-up to the general election, that the World Cup campaign was one of two priorities, along with the 2012 Olympics.
England's bid book is also expected to include key details on the supporter experience, with plans for family-only fan parks and a commitment to make a certain amount of tickets available at cheaper prices.
Expect the bid, which has not had the smoothest of rides, to also contain a series of pledges on financial assistance for football grass roots projects around the world.
Fifa has invited all the countries bidding for 2018 and 2022 - Russia, Spain and Portugal, USA, Australia, Qatar, Holland and Belgium, Japan and Korea - to submit their bid books on Friday. It is a key moment but the contents of each technical bid are far more important than the presentation.
No potential host will earn any extra points for speeches during the handover or flying the World's most famous footballer into Switzerland.
These campaigns ultimately rely on two things: a sound technical bid; and an ability to cut the right political deal with each of the 24 members of the Fifa executive committee who will make their decision in December.
The accepted wisdom is that the race for 2018 is between Europe and 2022 between Qatar, USA and Australia (Japan and Korea of course staged it in 2002).
England's focus on the financial benefits of their bid is designed to not only offer Fifa a less risky World Cup after South Africa and Brazil but to highlight less stable rivals such as Spain/Portugal and Russia.
But, as the bid now moves into a more intensive period of glad-handing and political dealmaking, none of that will count for anything if England do not get the lobbying right over the next few months.
