Schalke 04's nightmare start to the new German season continued on Saturday as they fell to a 2-1 defeat at Hanover.

The visitors were dumped out of the German Cup by third division Dynamo Dresden on Monday but Klaas Jan-Huntelaar's goal looked set to give them victory on the opening weekend of the Bundesliga.

Last season the Dutch striker's 12 goals helped Schalke finish third and he opened his account for the new campaign 90 seconds into the second half.

But the home side levelled 20 minutes later, when Leonardo Bittencourt surged down the right and picked out Edgar Prib.

Two minutes later Hanover got what proved the winning goal. Summer signing Joselu tried his luck from outside the box and the former Hoffenheim striker's shot took a slight deflection before nestling in the corner.

Elsewhere, Thomas Schaaf enjoyed his return to the Bundesliga as his Eintracht Frankfurt side beat visiting Freiburg 1-0.

Schaaf had taken a year out of football after spending 14 years at Werder Bremen and an early strike from Haris Seferovic gave him plenty to smile about.

After 15 minutes, the ball broke kindly for the Swiss striker inside the box and the 3.2 million euro summer signing from Real Sociedad slotted home the only goal.

Julian Schieber scored twice on his Hertha Berlin debut but the home side were held to a 2-2 draw against Werder Bremen.

Former Borussia Dortmund forward Schieber headed home a cross from another new signing, Dutch winger Roy Beerens, to give Hertha the lead after 16 minutes.

Hertha continued to create chances and deservedly doubled their lead when a cross deflected into Schieber's path on 47 minutes.

Assani Lukimya gave the visitors hope at the other end when he bundled home from a free-kick on 53 minutes and two minutes later Franco di Santo hauled Werder level.

Hoffenheim also scored two goals in three minutes as they beat Augsburg 2-0. The home team took the lead after 33 minutes after a scramble ensued when Augsburg goalkeeper Marvin Hitz failed to hold Roberto Firmino's cross shot.

The ball eventually fell to Hungarian striker Adam Szalai, who had a simple finish for his first goal since moving from Schalke in the summer.

Two minutes later, Firmino was again involved as Hoffenheim moved further clear. The Brazilian squared for Norway's Tarik Elyounousssi to score as Augsburg, who lost to fourth tier Magdeburg in the German Cup, slumped to another defeat.

Meanwhile chances were few and far between as newly-promoted Cologne were held to a scoreless draw at home by big-spending Hamburg.

On Friday, goals from Thomas Mueller and Arjen Robben helped defending champions Bayern Munich open with a 2-1 home win over VfL Wolfsburg.
