If someone needed more proof to the quality of the Bundesliga, Borussia Dortmund nailed the last of the remaining stakes into the bleeding heart of the Clasico duo, beating Real Madrid 4-1 in the first leg with an incredible performance from Robert Lewandowski, in what might be his final home appearance for the club in the Champions League.

Four goals, which one of them came from a sketchy penalty kick that shouldn’t have been whistled, but it didn’t really matter. Real Madrid weren’t as pathetic and welcoming as their biggest rivals 24 hours earlier, but there was no doubt regarding the better side. Luka Modric played in order to contain Mario Gotze, but on the way Real lost touch of Mario Gotze and Ilkay Gundogan, as the two simply steamrolled over the opposition’s midfield.

For a moment in the first half, when Cristiano Ronaldo made it 1-1 after a horrific defensive error, it looked like Jose Mourinho and his players knew what they were doing. Waiting for Dortmund to push forward and bite them with the most lethal counter attack player in the world. But the second half proved everyone wrong. Jurgen Klopp is the real genius, at lest at the moment, while his players, with a fantastic pressure and transition game, bullied Real Madrid across the pitch.

No one did it better than Lewandowski, maybe the only forward in the world strong enough to handle both Pepe and Raphael Varane, shrugging them off whenever he had the chance. Sven Bender did the same with his help on Cristiano Ronaldo, who wasn’t felt and couldn’t influence the match besides his equalizer, born out of a Dortmund mistake, not a Real Madrid thought or idea.

While the first and second goal for Dortmund might have been scored by anyone, the third showed just how good Lewandowski has become, and what a quality player Dortmund will lose this summer, probably his last with the team, showing amazing agility, balance and poise before giving the Alan Shearer celebration. It only got better later on with his fourth, while Real Madrid couldn’t really find their way into the Dortmund box.

A revolution in European football has begun, and will probably be finished by the end of the second legs. Borussia Dortmund might not be the best team in Germany, but in this kind of form, with Lewandowski at his best as well, they might be the best team left in the competition.
