1. Decorate your house with an appropriate tifo
2. Leave a copy of this on the coffee table to prove you know what you’re talking about
3. Have a ‘winner stays on’ FIFA Tournament for three hours before the game
4. Brush up on the meaning of ‘golazo’ and ‘tarjeta amarilla’ so you can impress your non-La Liga supporting mates
5. Make sure your guests are fed (and remind them that foodstuff is not to be thrown at ex-Barca players who’ve crossed the divide)
6. And don’t forget some beverages to wash it down
7. When the game starts make sure you’re watching on the biggest screen possible
8. But keep your smallest screen close to hand in case you need to Google a player
9. Have an Athletic Bilbao fan on hand to mediate any potential disputes
10. Whatever the result, don’t let the celebrations get out of hand
