Pep Guardiola wary of “incredibly dangerous” Pierre-Emerick Aubameyang

(CNN)Last December, the Bavarian bar Schumanns became the unlikely location for a meeting between two of football’s mightiest minds. This game can be viewed this Sunday on Fox Sports 2. By the hour mark, he had scored five times.

Few believe that any side but Dortmund can challenge Bayern for the title this season.

But as I previously stated, the players that he rested in the Europa League game will be in his lineup.

But that topsy-turvy campaign was enough to prompt Klopp to take his own sabbatical.

Borussi Dortmund, too, started the season brightly as they won their first five games, but have since drawn successive matches against Hoffenheim and newly-promoted Darmstadt.

The match was marred by clashes of Dortmund supporters with the police in the second half.

“It’s always a special game”, said Guardiola at his pre-match press conference on Friday. The striker won two free-kicks and provided an assist in a tireless display.

Franco di Santo scored a genuine hat-trick for Schalke putting three past the Greek defense from the 28th to the 44th minute, with Klaas Jan Huntelaar rounding off Asteras’s routing just before full-time. He just holds on to the ball like no one else.

BVB boss Hans-Joachim Watze spoke clearly of his frustration after the match.

“We see ourselves as challengers of teams who finished ahead of us last season in the league”.

Elsewhere, new manager Thomas Tuchel has managed to shake things up at Dortmund since taking charge. Every morning he wants his players to greet each other with a handshake, as if to say, “we’re looking forward to work today”.

“He has not trained with us”.

With his deal due to expire in 2014, Lewandowski signed a pre-contract agreement with arch-rivals Bayern Munich and has seen his stock continue to rise during his time at the Allianz Arena.

“I’ve missed more than 9,000 shots in my career”.

During his sabbatical, Tuchel never stopped working but traveled the world to glean new ideas.

“But he is approaching the final stages of his recovery process”. He needed that break to recharge and come back stronger.

Dortmund paid around €4.5m to acquire the 27-year-old from Polish side Lech Poznan in 2010, and he went on to score 74 goals during his four seasons in Westphalia. They are opponents now.
