That was one honest reply in my opinion. I liked it. At least he admitted that the refs help Barca on purpose. This is what separates blatant favoritism from refereeing errors, this is what separated Juve from the other big teams and this was exactly what made Ian changed his favorite team
Actually, that was only one of the reasons why he stopped being a Juve fan.
Another reason was buying mercenaries.
Ok, Ian later realized that Barcelona bought many mercenaries too, but Juve sell themselves to sponsors.
Ok, he later saw Barcelona's official site and saw hundreds of logos, including the Coca Cola logo..... but Juve didn't give a chance to youngsters while Barca does.
There, that's more than enough Ian to stay a Barcelona fan. They might be favored by the refs, they might sell themselves like whores, they might be buying mercenaries and paying 60 m eur for one player (who coincidentally is the biggest mercenary of them all), but at least they give chances to the youngsters.
Ok, Juve started doing it too, but still not as much as Barca.
There, that's where the difference is. Barca and Juve might be the same in everything else, but Barca have 2-3 more youngsters in the team and that's a big enough reason to be their fan and not to stop supporting them for the same reasons he stopped supporting Juve.
