Fair enough. Barcelona would have gladly kept him if it weren't for the money. They weren't allowed to offer him a professional contract until he turned 18 while Arsenal offered him a contract when he was just 16, am I right?
Yeah, could only offer him a youth contract, not a full contract... so lower pay, and as I recall, he also thought the prospect of first-team action looked better at Arsenal (obviously turned out to be true).
I don't think "Made in La Masia" is meant to be taken too literally. Like "Made in the US" means "Made in Taiwan", and "Made in Germany" means "Made in Taiwan". At least I hope they don't mean it too literally, but you never know with Sport/EMD.
