BR - As a preface to this article, let me just say that it was clear from the 180 minutes played in this Champions League quarterfinal that Barcelona posed a much greater threat to AC Milan, than vice versa.
Now that that's over with, let's point out the truth of the matter: that second penalty decision, gifted to Barcelona, ruined the tie.
It's funny how everyone is blaming 'Barca' for an error committed by Referee.
An article full of "ifs", "would've" etc. Even if the penalty wouldn't have been called, who's to say Milan would've not made yet another dumb foul in the box? Milan's defense, heck any team's defense can only cope with Barca for so long before they break, first leg okay, second leg you have to be prepared to fight fire with fire against Barca.
