The veteran goalkeeper misjudged a low, scuffed corner from Danilho Doekhi midway through the second half, allowing the ball to slip beneath him and trickle into the net.
Despite the setback, Neuer was the first to acknowledge his error after the match, demonstrating his accountability and leadership.
"I made the wrong decision in the first goal, we lost the second ball in the second goal. It was tough today against this team, especially after Wednesday,” Neuer told the media.
“But we believe we'll soon get back to winning ways. In the end I think it was a good point. We got a point and the competition didn't - and we're now six points clear.
“We struggled in defending set pieces today, and Union did well in that aspect."
