The Gamper Cup... a friendly cup Barca plays on Camp Nou every year before the Liga kicks off, against a random opponent, in honor of the club's founder Joan Gamper. It's always great fun since both teams (are supposed to) play nice and some one gets to take home a bright shiny trophy at the end.
The fact that Barca's Gamper opponent is AC Milan this time makes it even cooler - in part because they're a big club and facing their players is an exciting prospect, in no part because of the web of transfer talk that's heavily linking us and them at the moment, and in large part because it's Ronaldinho's first return to Camp Nou since he left two years ago.
Ronnie, who has issued an open letter to all culés for the occasion, is to be welcomed back with a tribute video by the club. That's awesome of them, and playing against such a huge legend of Barca will certainly be very interesting.
As to how Pep will approach this match, I say substitute participation since it'a friendly, with Bojan starting over Villa/Ibra and then one of the two subbed in in the second half. As for me, I'm counting down the minutes till the Ronnie reunion...
