Dietmar Hamann believes his Bayern Munich could be coming to the end of an era because the club's key stars are too old.
The Bavarian outfit have enjoyed an almost unprecedented run of domestic success in the Bundesliga, winning the league title four times in a row - with a fifth likely to follow in May.
They were able to exorcise their European demons in 2013 as they beat rivals Borussia Dortmund to claim the Champions League under former boss Jupp Heynckes - but were unable to follow up on that success under Pep Guardiola.
With captain Philipp Lahm announcing his retirement last week and pillars of the team such as Arjen Robben and Franck Ribery both well into their 30's, Hamann - who played for Bayern between 1993 and 1998 - is concerned that they're a club on the way down.
