Julian Nagelsmann said Bayern Munich "won't take any chances" with Robert Lewandowski's fitness when they face Freiburg on Saturday, with the striker nursing a rib injury.

The Bayern boss offered a promising update on Leon Goretzka's fitness, saying he would "love" to let the midfielder play, but could be left without Joshua Kimmich due to the imminent birth of his child.

Lewandowski netted a second-half penalty to set Poland on their way to World Cup qualification on Tuesday, opening the scoring in a 2-0 play-off win over Sweden.

The 33-year-old's last club outing saw him net twice against Union Berlin to reach 30 Bundesliga goals for a fifth time, a feat only previously achieved by the legendary Gerd Muller.

Ahead of the trip to fifth-placed Freiburg, Nagelsmann said that while Lewandowski is in the squad and in contention to feature, the club would act with caution after he picked up a rib injury. 

"We'll have to see how his rib reacts," Nagelsmann said.

"I assume he's in the squad and playing, but we won't take any chances."

If Lewandowski is deemed fit enough to feature, he could set an outright record for the most away goals scored in a single Bundesliga campaign. 

His current tally of 17 is a joint single-season record, shared with Jupp Heynckes (set in 1973-74 as a Borussia Monchengladbach player), and Timo Werner (2019-20 with RB Leipzig).

Meanwhile, Nagelsmann offered updates on the availability of two key midfielders, indicating that Goretzka is in line for his first appearance since December's 3-2 win over Borussia Dortmund.

He also revealed he has set a deadline for Kimmich to join up with the team as he awaits his child's birth.

"Goretzka reacted a bit on the hip, [but] otherwise he trained exceptionally well, and I would love to let him play," Nagelsmann added.

"I discussed with him [Kimmich] that if everything stays calm, he can travel later. We have set a deadline. The most important thing is that everyone stays fit. 

"We have a good squad and we have to control the players' workloads. At the same time, we need to keep our foot on the gas."

Bayern's tally of 81 goals from their 27 Bundesliga games is the best return at this stage of a season in the competition's history. Meanwhile, the perennial champions have scored in 74 consecutive Bundesliga matches, also a German top-flight record.
