Julian Nagelsmann expects normal order to be restored against Bayer Leverkusen as he backed Bayern Munich and Robert Lewandowski to get back on track this weekend.

Lewandowski's run of netting in 15 successive Bundesliga matches came to an end prior to the international break as he failed to find the net against Greuther Furth and then Eintracht Frankfurt.

It is the first time since November 2019 that the 33-year-old has gone scoreless in consecutive league games, and he also failed to find the net in Poland's World Cup qualifiers against San Marino and Albania over the international break.

The former Borussia Dortmund striker will be looking to put that right when Bayern travel to the BayArena, but his average of a goal every 225 minutes against Leverkusen is his worst record against all current German top-flight teams.

However, Nagelsmann is convinced the prolific marksman will return to the scoresheet in Sunday's top-of-the-table showdown, with Bayern only ahead of their opponents by virtue of a superior goal difference going into the weekend.

"Normally the situation takes care of itself when you take into the equation his quality and the number of chances we create," Nagelsmann said at Friday's pre-match news conference. "I expect things to return to normal again on Sunday.

"Of course I speak to him, like I do every other player, but mostly about the things that he can bring onto the pitch. Even a player like Robert can go a few games without scoring a goal." 

Lewandowski averages a goal every 225 minutes against Leverkusen

Bayern's unbeaten start to Nagelsmann's tenure came to a surprise end in their most recent match as they fell to a 2-1 loss at home to Frankfurt, with that also their first league loss at the Allianz Arena since November 2019.

The reigning champions now face a tricky trip to Leverkusen, but the omens are on the visitors' side.

In the past eight such meetings between the first and second-placed teams in Bundesliga, the league leaders have lost only once – Leverkusen against Bayern in this corresponding fixture last season.

Nagelsmann is not seeking excuses on the back of the Frankfurt loss, a game in which opposition keeper Kevin Trapp made 10 saves – the joint-most of any keeper in Europe's top five leagues this season – with full focus now on Leverkusen.

"It would be too cheap for me to say it was simply a case of the ball not going in in the last match," Nagelsmann said. "We played very similar to our other games this season, but on this occasion we didn't score four or five goals.

"We've spent time working on that. Over the course of several games, we will continue to work and deal with issues in the same way. On Sunday we can take the next step in our development.

"You can see Leverkusen have had good results and they have as many points as we do. I prepare for such a game by watching the opponents' matches, reading about them, watching interviews.

"I've learned about the good spirit they have. They have a good feeling of togetherness in their camp. But in the end we are looking forward to a top game and it is one we want to win."

Nagelsmann confirmed Lucas Hernandez is in contention to start against Gerardo Seoane's side, despite facing a six-month prison term for breaching a restraining order following a 2017 conviction of domestic violence against his then girlfriend.

Hernandez will attend court next week, but Nagelsmann has no concerns over the defender's mindset.

"I've experienced a normal player, not one with any negative effects," Nagelsmann said when asked about Hernandez. "If I hadn't read about the story, I wouldn't have asked about it.

"He's trained well again today and made a good impression. If he's healthy then he will play both in this game and the Champions League match against Benfica on Wednesday."
