FC Barcelona made the Round of 16 in the current UEFA Champions League (UCL). According to the FC Barcelona website, their possible rivals may be Galatasaray, AC Milan, Porto, Shakhtar Donetsk and Arsenal.
La Blaugrana will not face Celtic, who are also in Group G. Likewise, Real Madrid and Valencia CF will not face Barca because the clubs are all from Spain.
UEFA will hold a draw on December 20, 2012 for the Round of 16. The away leg dates will be February 12 and 13. The dates for the Round of 16 return leg will be February 18 and 19.
While La Blaugrana may be unstoppable in the current UCL season, rival clubs must not be underestimated. The situation for Barca is complicated after Messi bruised his knee in the club's match against Benfica.
A brief study of the possible rivals is in order.
