Thomas Tuchel said Borussia Dortmund's work on defense needs to improve after they let in four goals, despite an 8-4 Champions League win over Legia Warsaw.
Dortmund have established a two-point lead atop Group F, with Real Madrid in second, but manager Tuchel vowed that their defensive issues would be solved.
"Many mistakes were made by us," he said. "In the end, we managed to win. I am sorry for [goalkeeper] Roman Weidenfeller. The blatant mistakes that we have made, I will address."
"We left so much space in the defence, and we've got a lot of trouble with it."

Tuchel was in shock over the 8-4 scoreline.
"Apparently there has never been such a thing, so it is also difficult to analyze this game," he said. "It was surreal, I have never seen anything like that before."
It was a record-breaking night. No Champions League match has had more goals with Dortmund scoring from eight of their 10 shots on target and only five saves from both goalkeepers combined.

Tuchel was pleased with Marco Reus' return from injury.
"It is fantastic that Marco worked so well today. The game was not so intense that I would have to [substitute] him," Tuchel said.
"We had to wait a long time, much too long. It was an amazing comeback from him."
Reus had not played since sustaining a groin injury at the end of last season, but scored a hat-trick, while Shinji Kagawa picked up a brace in a span of only 76 seconds, the fastest double in Champions League history.

Another Champions League first was seeing eight players score in a single match.
Dortmund's next outing in Europe is against Real Madrid at the Santiago Bernabeu on December 7 in a game that will decide the winner of Group F.
