Munich - From dropped points to first wins, via free-scoring starts and new league leaders, once again the Bundesliga provided no end of talking points.

bundesliga.com rounds up five of the biggest stories from around Germany's top flight after Matchday 4.

The first three points of the Bundesliga season had been a long time coming for FC Schalke 04 - an opening day draw with Hamburger SV was followed by successive league defeats.

New VfB Stuttgart coach Thomas Schneider made his Bundesliga bow in style, guiding his team to a a 6-2 victory over local rivals 1899 Hoffenheim. Schneider was particularly impressed with joint Bundesliga top-scorer Vedad Ibisevic's hat-trick, and youngster Alexandru Maxim's brace. Meanwhile, hitherto free-scoring Hoffenheim have now conceded as many as they have scored (12) - but remain the ones to watch, averaging six goals a fixture.

The potential was already there, but Hakan Calhanoglu propelled himself to even greater heights on Matchday 4. The 19-year-old, who was Karlsruher SC's top scorer with 17 goals last season, opened his Bundesliga account for Hamburg with two outstanding finishes after coming off the bench against Braunschweig. The first, a demonstration of his dribbling skills and eye for goal, was then bettered by the second, a sumptuous free-kick which underlined his status as HSV's hottest prospect.

SC Freiburg's late equaliser saw FC Bayern Munich pass up the chance to maintain their 100% record, as they were knocked off top spot in the Bundesliga by longstanding rivals Borussia Dortmund. However, Nicholas Höfler's last-gasp leveller wasn't the only blow for the record titleholders this week with Bastian Schweinsteiger, Mario Götze, Javi Martinez and Arjen Robben having all been sidelined after Friday's taxing .

Henrikh Mkhitaryan bagged a brace against Eintracht Frankfurt to send Borussia Dortmund top of the Bundesliga. After Bayern's midweek draw, Leverkusen and 1. FSV Mainz 05 both passed up the chance to leapfrog the reigning champions on Saturday. Dortmund made no such mistake despite a few nervous moments, as they preserved their unblemished record with a fourth-straight win and another three-point haul against the Eagles.
