Julian Nagelsmann admits Bayern Munich must cut off supply to Barcelona’s Robert Lewandowski

Lewandowski has enjoyed a flying start to the season, having bagged nine goals in six games across all competitions.

Bayern boss Julian Nagelsmann underlined the threat posed by his former player in the pre-match press conference, saying: "I am looking forward to it, not so much as an opponent because he's very dangerous, but as a person I will be pleased to see him.

"I hope the fans will honour that too, regardless of how things were with his departure."

Nagelsmann added: "He is their most dangerous threat in front of goal. If he maintains the physical fitness he can play for sure a few more seasons at this level.

"In the last few years he has been scoring about 40 goals a year. He is on a good road towards achieving that this season.

"We have to stop passes and crosses to him. But there are several other very good players in that team as well."

When asked whether there would be any pre-match presentation, Nagelsmann seemed a tad bewildered, saying: "What's supposed to happen before the game? I'm interested?

"If I see him beforehand, I'm certainly ging to give him my hand. I'm not sure if I will see him beforehand. Usually, I don't. Usually that happens after the game.

"Our fans are going to be welcoming him back. He's been so strong for the team over the years. He was a great part of Bayern.

"We won't be going out for dinner beforehand, but we had a personal exchange a couple of weeks back. But I'm looking forward to seeing him again."
