Borussia Moenchengladbach's caretaker coach Andre Schubert still has no contract despite having equalled the record number of wins for a new Bundesliga coach on Saturday.

Gladbach's 4-1 win at Hertha Berlin on Saturday was their sixth since Schubert took charge in September, when they were bottom of the table after five straight defeats which led to Lucien Favre's shock resignation.

Schubert has now hauled Gladbach up to fourth and his six wins on his first stint in the Bundesliga equals the record Willi Entenmann achieved with VfB Stuttgart in 1986.

To give Schubert's remarkable run context, Bayern Munich's coach Pep Guardiola won only his opening three games in his first Bundesliga season in 2013/14.

"We're all just caretaker coaches -- I don't even have a contract," said Schubert of his backroom staff.

Gladbach host last seasons finalists Juventus in the Champions League on Tuesday.

While Schubert's results speak for themselves, Gladbach's director of sport Max Eberl hinted that he is likely to get the job permanently.

"We are successful. It is a good and clear situation and we will make a good decision," Eberl said.

Swiss international Granit Xhaka said the team want Schubert, who was promoted from Gladbach's youth team coach, to keep the job.

"When you win so much and pick up so many points, then that is also down to the coaches," said Xhaka.

"We would like to keep him.

"We can only put in our performances on the pitch, the board has to decide everything else."

In his nine games and 40 days in charge, Schubert has lost just once, 2-1 at home to Manchester City in the Champions League.

They have won seven matches, including knocking Schalke out of the German Cup and earned a Champions League point with a goalless draw at Juventus.

Schubert is the coach of Germany's Under-15 team and had only previously worked in the second division at Paderborn and St Pauli at senior level.

But his Gladbach side is playing with confidence as they blitzed Hertha with two goals in as many first-half minutes at Berlin's Olympic Stadium.

Left-back Oscar Wendt put them ahead, then a solo effort from Brazil striker Raffael made it 2-0 after 28 minutes.

Gladbach grabbed a third when Xhaka drilled home a penalty on 55 minutes after Ivory Coast winger Ibrahima Traore was fouled in the area.

Alexander Baumjohann converted a late penalty for Hertha after being fouled before Havard Nordtveit grabbed Gladbach's fourth in added time.

The result boosts Gladbach before they face Juventus.

"Now comes the Champions League, and there's every reason I'll still be here, I think," said Schubert.

"For anything else, you have to ask Max Eberl.

"I'll do this job as long as I can.

"I am enjoying working with the team and I like working in professional football, but it's not something I have to do."
