Probably i'd have a house with a big football pitch out the back, and all the training stuff, i'd practice extra a lot. Work on my weaker foot, shooting, free-kicks etc. Maybe run some stuff for local kids too.
I'd also probably try and set-up a couple of small businesses, nothing major, maybe in the farming/food industry, produce some locally grown/made goods, maybe combined with a shop. Just for interest and personal satisfaction, it wouldn't really need to make a profit.
I'd probably pay some really good chef guy to teach me to cook better too (i'd have a big garden just for growing food, with chickens and stuff too, i'm useless at gardening but i'd get someone else to do that too).
Probably get involved in some conservation charities as well.
