Surely £20 includes the book as well?
20 quid plus the cost of the book (if you choose)? Maybe they'll have a Hero or two there, Tayls and Tonev etc. Make sure you ask him a searching question, you were born for this.
Twenty quid? You could buy the Witton Arms for that much once.
I think Guillem puts the money towards Biggleswade FC, he's involved with them as a director or chairman. He's been there quite a while, may even have brokered Keinan Davis' move to Villa. Maybe ask him about that, show a bit of geek-Villa flex.
