Since last coming home in the 1966, football has travelled extensively, including extended spells in South America visiting Brazil and Argentina. It almost came home in 1990 and again in 1996, but both times made late decisions to go to Germany instead, where it spends so much time it has actually bought a second house.
While a cup of tea and a biscuit would be lovely if football does come home, don't go so far as to plan dinner around it, as there is a chance it will decide to pop over to Italy for a few years instead.
