Thomas Tuchel was left to rue an error-prone performance from his Borussia Dortmund side tonight.

The Germans lost 3-1 to AS Monaco at the Stage Louis II to bow out of the Champions League 6-3 on aggregate at the quarter-final stage.

Early goals from Kylian Mbappe and Radamel Falcao killed off any Dortmund resistance before Marco Reus and Valere Germain traded second-half goals in the Principality.

"We started well with one or two dangerous moves where we found some space and then conceded an unlucky goal," said Tuchel.

"That destroyed our belief a bit. Then we made too many mistakes in our passing and positioning.

"In the second half we tried to rally again, but we were never able to follow up on our goal. We have made great games with a back three, especially in the Champions League, but we were not good enough.

"Altogether, our performance was not up to it."

He added: "Our mistakes helped them to two early goals, which made things even more difficult.

"We tried everything after the break and I think we put in a good performance then, but it was over after their third goal.

"The first goal was my mistake, I should have used my fists to push it further away."
