Louis van Gaal believes Jupp Heynckes would become a Bayern Munich legend if he retires at the end of the season.
Heynckes is currently enjoying his fourth stint as Bayern head coach, having taken over from the sacked Carlo Ancelotti in October.
The 72-year-old has made a huge impact on Bayern's fortunes, with the club 17 points clear of second-placed Schalke at the top of the Bundesliga, with a DFB-Pokal semi-final and Champions League quarter-final coming up.
Heynckes only has a contract until the end of the season, but the prospect of him remaining in charge for the 2018-19 campaign has been raised repeatedly and the coach says he is yet to make a decision regarding his future.
