Hertha Berlin coach Jos Luhukay is in danger of becoming the fourth coach sacked in the Bundesliga this season after his side slipped into the relegation places.

Their 1-0 defeat at home to Bayer Leverkusen on Wednesday left them second from bottom of the German league as they finished with ten men after Sebastian Langkamp was sent off in the 90th minute for a second yellow card.

They have lost their last three games and have won just two of their last ten matches.

They are away to Mainz on Saturday and director of sport Michael Preetz refused to say whether Luhukay will be in charge.

"I can't tell you. We need to analyse and sleep on it and then we'll talk," Preetz told Sky after the Leverkusen defeat.

"We aren't naive and we can read the table.

"We have now slid down the table and the alarm bells have been ringing for a while."

Hertha started 2015 in poor fashion with a 2-0 defeat at resurgent Werder Bremen on Sunday after being hammered 5-0 at home to Hoffenheim in their last game before Christmas.

"I assume that I will be preparing as well as possible over the next two days for the match against Mainz," said Luhukay when asked about his future.

The 51-year-old Dutchman took charge in July 2012, while Preetz was director of sport when they were relegated from Germany's top flight in 2010 and again in 2012.

A possible dismissal would make Luhukay the fourth German league coach to be sacked this year.

Bremen dismissed Robin Dutt in October, Mirko Slomka was released by Hamburg in September and Jens Keller was shown the door at Schalke in October.
