The pair have met in two of the last four Champions League finals, plus the 2008 semi-final.
More recently, they met in Washington last summer as part of pre-season preparations for the 2011-12 campaign.
One notable absentee will be Ryan Giggs, who is due to be confirmed as an over-age player in Stuart Pearce's GB Olympics squad when it is announced early next week.
Already knew, don't like watching Barca's pre-season games though, they are painful to watch, especially if they play in the U.S. I remember when they were beat by Chivas or some crappy team like that here in the states, I think the coaches stress the importance of not getting injured to the players, so they play like crap.
i seriously doubt after the season they've had including the euros and spain their best players will even come on the tour.
Beat them last time :)
