The BVB boss was left livid after his side slipped to 17th in the Bundesliga table and is now hoping that the winter break will bring about a change in fortune
Teenage forward Davie Selke gave the hosts an early lead, which was doubled just after the hour mark by strike partner Fin Bartels.
Mats Hummels pulled one back for Dortmund but Viktor Skrypnyk’s side held on to claim a victory that moved them off the bottom of the Bundesliga and dropped BVB down to 17th place.
Unsurprisingly, Klopp is now praying that upcoming winter break will re-energise his struggling side.
“The best news today is that football is over for 2014,” the Dortmund boss told Sky.
“Any criticism that we receive now is justified. We are standing here like complete idiots and it’s completely our own fault.
“We now have three weeks of preparation ahead of us. Then we will repair what we’ve done.”
Dortmund resume Bundesliga action after the winter hiatus with a tricky trip to Bayer Leverkusen on January 31.
