|Football's round the world journey|
|Around the Academy:
Imagine a Chinese army 2,200 years ago zooming in a time machine to one of our football stadiums on Saturday afternoon.
What would they make of all the fuss? Some believe the origins of the beautiful game began with this fine bunch of sportsmen.
And as they watched the game they might be forgiven for thinking that football hadn't changed that much.
But there are loads of different theories on who invented the sport.
Did it come from Asia all those years ago? What about the Romans? Perhaps it was the idea of some university students punting down a river?
Or was it the workers from north England kicking pig bladders around the muddy fields? We do know the first club formed was in Sheffield.
All of these people can probably claim to playing a small part in the creation of football.
Find out how the game has progressed from bamboo goal posts to a sport played by millions across the whole world.
