While understandably disappointed, the goalkeeper was joined by team-mate Mats Hummels in lauding his team's spirit right to the final whistle
The 32-year-old's heroics between the posts were crucial in keeping his side afloat throughout the encounter, only to be undone by Mario Mandzukic's opportunistic tap-in and Arjen Robben's 89th minute winner.
And the keeper hailed his team's fighting spirit for matching the eventual champions blow-for-blow for the majority of the match.
"We’re proud to have given Bayern a real game tonight," Weidenfeller noted to pitchside reporters after the game. "We played well but it wasn't meant to be.
Team-mate Mats Hummels weighed in with his own acknowledgement of BVB's effort, only lamenting the cruel turn of events in the proceedings leading up to full-time.
"We feel pride but also disappointment when you lose a match in the 90th minute," the former Bayern stopper reflected to ZDF.
"But we were a little tired at the end and Bayern took advantage of that. We didn't have enough possession and it told in the end.
"It’s hard to lose like that."
