Manuel Neuer's eventual exit from Bayern Munich will be a "bigger problem" than Robert Lewandowski departing, according to former boss Felix Magath.

Neuer joined the Bavarian side from Schalke in 2011 and holds the record for the most clean sheets in the Bundesliga (209), having surpassed Oliver Kahn (196) in 2021.

The Germany international's contract is due to expire at the end of the next season, when he will be 37, leading to speculation over his future at Julian Nagelsmann's team.

The goalkeeper has been absent in recent weeks after undergoing knee surgery, coinciding with a downturn in Bayern form.

Nagelsmann's side were downed 4-2 by Bochum in their first game without their captain and were then held by Salzburg before ending a poor run of form with a 4-1 win over Greuther Furth last time out.

Neuer returned to light training on Monday and Magath, who completed consecutive doubles in charge of Bayern between in the 2004-05 and 2005-06 seasons, believes the 35-year-old is more important to the reigning Bundesliga champions than talisman Lewandowski.

"Bayern and the national team live strongly from Manuel Neuer," Magath said to German outlet Kicker, adding: "Marc-Andre ter Stegen can be very good, but he doesn't have Neuer's charisma. Manuel is a stroke of luck for German football."

When pushed for a comparison between Neuer and Lewandowski, Magath responded: "It will be a bigger problem for Bayern when Neuer is gone."

Neuer helped Bayern earn a 3-2 home win over RB Leipzig in his last outing, as he matched Oliver Kahn's all-time record of 310 Bundesliga wins by a player. He achieved the first 77 wins with Schalke.

Meanwhile, Lewandowski has again been in scintillating form this campaign, scoring 39 times across all competitions – 14 more than any other player across Europe's top-five leagues.

The Poland forward currently finds the net once every 71.2 minutes on average, with only Borussia Dortmund's Erling Haaland managing goals at a faster rate among those to have scored 15 or more in the same group.

While Neuer's return date remains unconfirmed, Lewandowski will hope to continue his prolific term as Bayern look to extend their six-point advantage at the Bundesliga summit when they face Eintracht Frankfurt on Saturday.
