"After losing 6-1, you have to lower your sights for a time," Hecking told reporters on Tuesday. "We actually did plenty of things right tonight, but at the end of the day you're confronted by the result.
"Obviously it's not to our taste, but we have to accept it. We did many things really well, especially in the first half. We had chances, but if so, you've got to put them away.
"I'm gutted we were hit on the break for three of the first four goals. But Bayern are ruthless and it's hard to defend against that. What remains is the 6-1 scoreline, two or three goals too many in my opinion."
The other semi-final is between Stuttgart and Freiburg and it will be played out on Wednesday.
