Someone do a cheat sheet of ‘other sports’ for me-

The equivalent of this for football:

Dominant force in England for past few years: Man United
Nearest challengers: Man City
Other contenders: Chelsea, maybe Arsenal
Has-beens: Liverpool
Dominant force in Europe for past few years: Barcelona
Dominant force Internationally: Spain
Best player in the world: Messi

Rugby Union? Rugby League? Cricket? American Football (obvs changed accordingly)?

PS. If anyone disagrees with my football ones, they’re just obvious examples, so you can stop throwing stuff at me.
