(CNN) Its motto is "More than a club" and Spain's Barcelona produced more than a result Wednesday routing France's Paris Saint-Germain 6-1 to qualify for the Champions League quarterfinals. Barca is the first team to overturn a first-leg 4-0 deficit in the history of the Champions League. Former Bayern and Chelsea star Michael Ballack tweeted: "That's Champions League," followed by a series of fire emojis. In the 2005 Champions League final, Liverpool came back from a 3-0 halftime deficit to beat AC Milan on penalties, but Barca's victory is arguably the greatest comeback in the history of the Champions League, given those frantic and frenetic final seven minutes. Even so PSG's owners, management, players and fans will all be left wondering just how they exited the Champions League given their commanding first-leg performance and big lead.
