Bayern Munich coach Jupp Heynckes felt his team gifted Real Madrid their 2-1 win in the Champions League semi-final first leg on Wednesday.
After Joshua Kimmich gave Bayern the lead at Allianz Arena, goals from Marcelo and Marco Asensio helped two-time reigning champions Madrid to an away win.
The Bundesliga champions failed to clear the ball on Marcelo's goal, while Rafinha's turnover led to Asensio's second-half strike.
Heynckes lamented the way Bayern conceded and his side's inability to make the most of their chances, giving them work to do ahead of next week's second leg.
"We gave Real Madrid two goals with clear mistakes," he told ZDF.
