Barcelona seem to be very lucky been grouped with Porto, Sharkhtar and Antwerp because clearly they are dominating in the group winning all three first legs and leading with nine points with Porto following behind with 6 points. It doesn’t look like Barcelona will lose even a game in this group, their future in the UCL this season looks very promising.
I believe that you made this statement before the Barcelona vs Real Madrid in the weekend where their we're defeated by a goal difference, although the overall performance of Barcelona in the Champions League has been very impressive bit in the other leagues such as the La Liga, the club is already gradually falling behind in the number of won games.
But if it is the UEFA then we can bank on the Barcelona squad to do something very impressive and much respected by the fans and even the other football spectators who may be interested in seeing the club win.
