Happy homecoming

Thomas Tuchel made a triumphant return to former club 1. FSV Mainz 05 on Friday night. Looking to arrest a four-match winless run in all competitions, his Borussia Dortmund side survived the occasional wobble in an eventual 2-0 win in Matchday 9’s opening fixture. Pierre-Emerick Aubameyang failed to find the net for the first time in ten Bundesliga matches dating back to last season, but chipped in with assists for Marco Reus and Henrikh Mkhitaryan.

Nine and counting

Saturday’s 1-0 victory away to SV Werder Bremen saw the defending champions become the first team in Bundesliga history to win their opening nine games of the season. Thomas Müller scored the only goal in a workmanlike display at the Weser Stadium with the men from Munich now victorious in their last 43 Bundesliga matches in which the so-called Raumdeuter has found the net. For Bremen, five successive defeats equals a rather unwanted club record.

The Schubert effect

The 2-1 Matchday 3 loss to struggling Bremen must seem like a lifetime ago for Borussia Mönchengladbach. Vanquishing Eintracht Frankfurt to the tune of 5-1, the Foals made it four Bundesliga wins on the bounce under caretaker marvel Andre Schubert, who only took over from Lucien Favre three weeks ago with the club rock-bottom of the table. The defeat, meanwhile, brings an emphatic end to Eintracht’s 14-match unbeaten Bundesliga run at the Commerzbank Arena.

Kruse does it again

After notching the goal that secured Germany’s path to UEFA EURO 2016, VfL Wolfsburg striker Max Kruse went into overdrive against TSG 1899 Hoffenheim on Saturday afternoon. The former Gladbach forward was on target inside the opening minute at the Volkswagen Arena, before completing his hat-trick with a second-half brace. The game ended 4-2 in the Wolves’ favour as Dieter Hecking’s side ended a run of four matches in all competitions without a win.

Schalke mean business

What an emotional rollercoaster ride FC Schalke 04’s clash with Hertha Berlin turned out to be for all concerned. Pal Dardai’s Hertha were reduced to ten men after 18 minutes when Vedad Ibisevic received a straight red card for an ill-advised lunge on Max Meyer. Schalke made the most of their numerical advantage as captain Benedikt Höwedes powered in a first-half header, only for Salomon Kalou to restore parity 17 minutes from time. The Royal Blues kept plugging away, though, and were rewarded in added time when Meyer poked in a dramatic winner to ensure his side remain just a point behind second-placed Dortmund after nine matches.

Leverkusen firing blanks

Eighth-in-the-table Bayer 04 Leverkusen fell further off the top-four pace after being held to a frustrating goalless draw by Hamburger SV. HSV custodian Rene Adler played an absolute blinder against his former club, but that should not detract from another toothless showing in front of goal from Roger Schmidt’s side. With a meagre eight goals in nine matches so far in 2015/16, die Werkself have now been outscored by every outfit in the division save FC Ingolstadt 04 (6) Bremen (7), Hannover 96, FC Augsburg and Hamburg (all 8).

Lilies in bloom

Promoted SV Darmstadt 98 continue to make a mockery of their ‘relegation favourites’ tag in their first season back in the big time for 33 years. First-half goals from Sandro Wagner and Peter Niemeyer were enough to see off lowly Augsburg on Saturday as the Lilies extended their unbeaten away run this season to four Bundesliga matches (W2, D2). Over a quarter of the way into 2015/16, Dirk Schuster’s energetic posse sit eight points clear of the bottom three.

Hannover on the up

1. FC Köln suffered their first defeat at the RheinEnergieStadion since 6 December 2014 at the hands of rejuvented Hannover 96 on Sunday afternoon. Leon Andreasen netted the decisive goal after 38 minutes as the Reds moved out of the relegation zone for the first time since Matchday 3, extending their unbeaten run to three matches in the process.

Stuttgart off the mark

VfB Stuttgart likewise moved out of the drop zone on Sunday thanks to their 1-0 victory at home to FC Ingolstadt 04. Daniel Didavi (pictured) got the goal that handed the Swabians their first win at the Mercedes-Benz Arena under new coach Alexander Zorniger, and their first clean sheet of the campaign to boot.

Triumphant debut

Former Bayern midfielder Stefan Effenberg (l.), the self-styled "New One" in the coaching game, made a successful start to his fledgling career on the touchline by guiding Bundesliga 2 side SC Paderborn to a 2-0 home victory over Eintracht Braunschweig. It was SCP's third win of the campaign, but they still have a long way to go before pulling clear of the bottom of the table.
