3 things we learned in the Bundesliga this weekend: Chicharito sets European scoring record

With another weekend of Bundesliga action in the books, we take a look back at some of what we learned from the latest slate of matches.

Chicharito makes European history

There's no telling where Bayer Leverkusen would be without Javier Hernandez, a one-man wrecking crew in front of goal since his loan move to Germany from Manchester United.

The Mexican forward is proving to be one of the top summer additions to the Bundesliga thanks to his lethal finishing in front of goal, an aspect he'd failed to master in England and during his brief spell in Spain with Real Madrid.

Hernandez, affectionately known as Chicharito, bulged the back of the net twice to help Leverkusen triumph over Eintracht Frankfurt and extend his remarkable scoring run in all competitions.

The brace brings Chicharito's haul to 12 goals in 13 matches and moves the forward into a class of his own as the first Mexican to find the back of the net in seven consecutive games.

Wolfsburg dominant at home

Few teams will be eager for the trip to an away fixture at the Volkswagen Arena, as VfL Wolfsburg's dominance over the past two years has often led to disappointment for the travelling team and its supporters.

Werder Bremen was the latest to feel the wrath of the host after a 6-0 thrashing preserved Wolfsburg's unbeaten record at home.

While Bayern Munich and Borussia Dortmund are also unbeaten at home, no team in Germany's top flight can match Wolfsburg's performance over the past season and a half.

The club has gone seven matches without a loss to extend a streak that dates back to the 2013-14 campaign. Wolfsburg has not lost in 26 successive home matches, a run that started after a 6-1 thumping at the hands of Bayern Munich in March 2014.

Mats Hummels' struggles mounting

The struggles plaguing Mats Hummels reached a climax after his own goal contributed to Borussia Dortmund's surprising loss to Hamburg SV.

It's been a season filled with criticism for the World Cup-winning centre-back, and the weekend's backlash set Hummels off.

"All that totally overblown criticism," he said on Twitter, with translation from ESPN.

"Unbelievable what you have to put up with. Blown out of proportion with reality."

The problem for Hummels, and Dortmund as a whole, has come away from home: The club's impressive defence at the Westfalenstadion has been eclipsed by a run of seven away matches that's seen Dortmund's backline concede 12 goals.
