I doubt there will be several goals, like 8, in this second leg meeting of Barcelona and Atletico Madrid, like we have them in the first leg meeting.
There are a lot of improvements in Barcelona's defense line than they had last month when Barcelona had a 4-4 draw with Atletico Madrid. If you have studied Barcelona matches from that time till now, you will notice that Barcelona has built their defense line to be good, not to concede more than goals. The highest goals Barcelona has conceded is only 2 goals, and it is from Atletico Madrid. Their goal margin against their opponent is from 3-4 goals above.
Athletico is good when it come to defensive game play, they do this .making their opponent attack more and then they find a perfect moment to create a dangerous counter attack. It works so much for them somehow... They used it in their last laliga against Barca(yes that 4-2game), if not because solorth missed a clear chance then the game could have ended 3-3 somehow (maybe). I still think there coul be some goals but at most maybe 5~6.. it's the last trophy Athletico can ever hope for this season and maybe used it to get a revenge against Realmadrid

yet they still need to fight for it, let's see how it goes.
