Heh, that might be true...! You get the sense some of these guys haven't cared about anything else since they were like 5 years old. I think about that when some footballers are asked about their favourite artist/film/etc - and the struggle really seems just to be able to come up with a believable answer. Anyway, I have the feeling the main hobby for a lot of footballers is their family... Which is fine! But I think even someone like Arteta (assuming he's generally a 24/7 football guy), spends several hours a day not reading tactical analysis - but hanging out with his kids, gardening, cooking, ...I don't know. At least I hope he does!
