BVB Dortmund boss Thomas Tuchel says there are no concerns about his side's recent defensive lapses in their 3-2 derby win over Schalke on Sunday.
Klaas-Jan Huntelaar netted both his side's goals after latching on to defensive errors, particularly one from Sokratis Papastathopoulos for the opener.
Tuchel, though, was relaxed about the error, claiming that such mistakes do happen every so often.
"We initiated two times goals against us with our own mishaps," he said. "That happens maybe one time a year.
"Papa told me he has seen the ball late, so he could only try to get his leg there. That’s how it looked like in the end. S*** happens."
Tuchel didn't want to criticise Mats Hummels for his mistake, which led to the equaliser, either, insisting the Germany international was right to pass out from the back.
"Mats had a great idea, wanted to pass into the attack with his first contact after picking up the ball – a behaviour, that we want and that distinguishes Mats," he added.
