Barcelona doesn't even need to try but barcelona must win against intermilan if barcelona wanna go to the next round. There's no choice for barcelona other than winning the game or barcelona will lose a chance to go to the next round.
Barcelona will have a very big cap if barcelona will be losing against intermilan. Remember that only 2 rounds remaining if barcelona will lose against intermilan. That gives no chance for barcelona.
Yeah it's seems no chance for Barcelona can enter the next round if they lose against Inter Milan again, because both Inter Milan and Bayern Munich will have a match against Viktoria Pizen which I think a free points for them. Maybe there's a chance Inter Milan and Barcelona points are same, but the thing is Barcelona is losing by the aggregate and other stats. Barcelona must win or at least draw on their next 3 matches, also they need to hope Inter Milan lose against Bayern Munich.
my prediction for Barcelona to not qualify for the next round is still alive, but i have to admit that it's tough right now for Inter to get 2nd place, if they were able to get a draw out of Bayern Munich in Milan there chances could have been way better now, but there is hope still, if they lose against Barcelona it's over, but a draw could make things really interesting.
