The largest football stadium in Britain, Wembley has 90,000 seats. If they were placed end to end they would stretch 54 kilometres (33 miles), roughly the distance from Liverpool to Manchester or Cardiff to Swansea.
Wembley's size reflects how football in Britain is big business. The Premier League is the most lucrative in the world, with income coming from the huge attendances at matches and the TV rights that follow.
The top clubs turn over up to £500 million a year, with the combined revenue of the 20 Premier League clubs reaching over £4.5 billion.
Devotion to the game
Over 14 million fans attended 380 Premier League matches in the 2017/18 season. Manchester United attract the largest crowds, with home games drawing in 75,000 people.
On average British fans devote the equivalent of a whole month each year to supporting their team. That's 15 hours every week. And for 1 in 10 fans, that rises to more than 30 hours a week. This includes everything from travelling and watching games to talking about it with friends.
The average weekly salary in Britain is just over £500 (£26,500 per year). While £100 seems like a lot to most of us, its very little to many professional footballers. Premier League players have an average basic salary of around £2.3m a year (£43,000 a week).
The figure rises to a startling £12+ million a year for the very best players. And that is before extra income from advertising and other branding deals. This figure puts them at the very top of the salary tree, above most of the corporate leaders.
Although the very highest incomes can seem excessive, they are only earned by a tiny number of people. If you have a salary of £45,000 that just puts you into the top 10% of incomes in Britain; £60,000 gets you into the top 5%; and £120,000 into the top 1%.
