Terry Pratchett 
Unseen Academicals 
(Discworld Novel 37)

”We play and are played and the best we can hope for is to do it with style.”
Football has come to the ancient city of Ankh-Morpork. And now the wizards of Unseen University must win a football match without using magic . . . so they”re in the mood for trying everything else.
To do this, they recruit an unlikely group of players: Trev, a street urchin with a talent for kicking a tin can; Glenda, the night chef who makes a mean pie; Juliet, the kitchen hand turned world”s greatest fashion model; and the mysterious Mr Nutt, who has something powerful, and dark, locked away inside him . . .
And the thing about football – the important thing about football – is that it is not just about football. Here we go, here we go, here we go!
”This isn”t just football, it”s Discworld football. Or, to borrow another phrase, it”s about life, the Universe and everything” The Times
”No one mixes the fantastical and mundane to better comic effect ” Daily Mail
