He made his debut for the club in March 1991, as a substitute for Christian Ziege in a European Cup match against FC Porto, and added two Bundesliga appearances under Jupp Heynckes before the end of the season as Bayern finished in second place.

Münch spent two very successful years with Beşiktaş, scoring 6 goals and 22 assists while winning the Atatürk-Cup and finishing second and then fourth in the league, before returning to Germany to sign for Borussia Mönchengladbach, who had just been promoted back to the Bundesliga.

He currently trains around 30 racehorses at Chantilly, France and was previously based in Mannheim and Frankfurt, Germany where he had some successful years early in his career, despite only starting with a small amount of horses, including the filly Intarsia, who won Münch's first „Listed race“ in 2010.

In 2016, following his move from Frankfurt to Chantilly, he had huge success training the self-bred three-year-old filly Spectre to win the Group Three Prix Imprudence at Maisons-Laffitte.

Spectre went on to make her Group One debut in the Poule D‘Essai des Pouliches at Deauville where she finished fifth only being beaten by 1 1/2 lengths to La Cressonniere.

Spectre's best career performance came in early September, where she finished as a runner-up to Vadamos in the Group One Prix Du Moulin, while beating some high-class colts such as Zelzal and Zarak.

During the early years of his career in horse racing, Münch was also associated with the german Preis der Diana winner Feodora (2014) and the Deutsches Derby runner up Palace Prince (2015).
