[1] While Lattek was preparing for a career as a teacher, he played football with SSV Marienheide, Bayer Leverkusen and VfR Wipperfürth.

To a team already boasting Beckenbauer, Gerd Müller and Sepp Maier, Lattek added the young talents of Paul Breitner and Uli Hoeneß, ushering in a period of near dominance for the Bavarian club.

A poor start to the 1974–75 domestic season saw Lattek's tenure come to an end, with Bayern replacing him with Dettmar Cramer, who was also recommended to the club by Beckenbauer.

This spell saw him win two more German titles, in addition to achieving further European success with victory in the 1979 UEFA Cup final, defeating Red Star Belgrade.

Liverpool declined to participate in the ensuing matches for the Intercontinental Cup, so Borussia took their place against South American champions Boca Juniors in the final.

In his time at Mönchengladbach he had managed legendary striker Jupp Heynckes (226 goals in 375 league matches / 51 goals in 64 European competition matches), along with great Danish forward Allan Simonsen and such national team stalwarts as Berti Vogts, Rainer Bonhof, Uli Stielike, and Herbert Wimmer.

His 15-year-old son also died from leukaemia at that time, leading him to seek a different working challenge as a distraction from the grief in his personal life.

Lattek got his next managerial appointment from his former player Uli Hoeneß, who was by then in charge as commercial manager with his old side, Bayern Munich.

Great players during his second stint with Bayern included Karl-Heinz Rummenigge, Lothar Matthäus, Klaus Augenthaler, Dieter Hoeneß, the Danish midfielder Søren Lerby and the Belgian national goalkeeper Jean-Marie Pfaff.

Lattek officially retired and took up a role as TV commentator and newspaper columnist with the national broadsheet Die Welt and the bi-weekly sports magazine Kicker.

The club had won the 1997 Champions League title, but was in panic mode towards the end of the 1999–2000 season, just one point above the relegation zone with five matches left to play.

At Dortmund he left a working base for his successor Matthias Sammer, who two years later at the age of 34 became the youngest coach to manage a German team to the league championship.
