Well, I am a very positive person and I do believe in a comeback Tomorrow Madrid must score at least 2 goals in the first 15 minutes and must tie the game in the first half.
Im just waiting to see how things will be like when Arsenal score the first goal in the opening 5 minutes of the game

Or if the first half ends in a goalless draw.
Except Arsenal go there scared, Madrid won't do any comeback. I doubt they will even put up a great performance. Talking and making social media post is one thing, playing on the field is anther thing.
Their is no excuse for Barca's loss, Dortmund playing at home is not an excuse for Barca to lose the game or did they expect Dortmund to play bad at their home stadium? No I expected a challenge but I didn't expect Barca to be this weak. No one expected Dortmund to win the game to qualify but they did well to at least win the match and that's what impressed me because Barca have been in top form lately and a struggling Dortmund was able to win against them in full game time.
Do you people think football is played on paper? You see a team in better form than the other and assume they're going to thrash the other team?
Dortmund have lost 4-0 already, they have nothing else to lose, so they will put in all they have into winning the game and even if they can't qualify, they will give their fans something.
Did you watch the match? You couldn't see that Barcelona players were fatigued and needed rest? And playing away from home in the UCL is always difficult, talking more of playing in front of the yellow wall.
It's not a shock for Dortmund to win Barcelona; it would have been a shock if Barcelona somehow failed to qualify after winning 4-0.
