Although his successor on the Bayern Munich bench has already been announced as Pep Guardiola, Jupp Heynckes heaped praise upon Mainz's coach Thomas Tuchel, saying he will no doubt be Bayern coach in the future.
The two teams face each other on Saturday in the Bundesliga with Heynckes' side still occupying top spot in the league, while the hosts are currently fifth after performing well so far.
And Heynckes believes it is in no small part down to the work put in by Tuchel at the Coface Arena outfit this term, which he insists will ensure the Mainz boss will eventually become a trainer at die Roten.
"He is a coach who is destined to eventually train Bayern," Heynckes told reporters.
"He has done a very good job, I have sufficient experience of him to know he's a great coach."
