Julian Nagelsmann is too young to be the next Bayern Munich coach and the club needs to consider its philosophy to find a long-term successor to Jupp Heynckes, says goalkeeping great Oliver Kahn.
Heynckes came out of retirement to take charge of the Bundesliga giants last month following the sacking of Carlo Ancelotti, the veteran immediately overseeing four straight league wins, including Saturday's Klassiker triumph away to Borussia Dortmund.
But the 72-year-old only signed a deal to the end of the season and has indicated he would not want to be in charge long-term, having left the club in June 2013 after completing a historic treble.
