Just for reference....Barcelona's home record in the Champions League this year:
Barcelona 7 - Celtic 0
Barcelona 4 - Man City 0
Barcelona 4 - Monchengladbach 0
Barcelona 6 - PSG 1
So, so far in the champions league they have only conceded 1 goal at home and on average have scored over 5 goals. All 4 of their home results would be satisfactory in order for them to get to the semi finals.
This barca team may not be as good as Guardiola's one (which was overall much more complete and hard working). However, this Barca team has goals in them.
Make no mistake. This is still a VERY difficult match for us. We need to score twice as Allegri said. Sitting back and going for the break is something that I think all 4 of their opponents have tried. We need to be balanced and look to attack when needed just like we did in the 1st leg - We have to IGNORE Camp Nou and assume its just any other game.
