Former Bayern Munich, Borussia Monchengladbach and Barcelona coach Udo Lattek has died at the age of 80.
The German had been suffering from Parkinson's Disease and dementia.
Lattek is best remembered for his two stints at Bayern, during which he guided the club to their first European Cup triumph in 1974.
He was also part of the coaching set-up that took West Germany to the final of the 1966 World Cup, where they were beaten by England at Wembley.
Lattek achieved the rare distinction of coaching clubs to all three major European titles, winning the Uefa Cup with Monchengladbach in 1979 and the Cup Winners' Cup with Barcelona in 1982.
He also had spells in charge of Borussia Dortmund, Cologne and Schalke.
"We are deeply moved and affected by the news of Udo Lattek's death. His name is so closely associated with the rise of FC Bayern in the successful 1970s," Bayern chairman Karl-Heinz Rummenigge said.
"Udo Lattek was one of Germany's most successful football coaches. As well as this, he was one of the sport's biggest personalities, at home and abroad, for many decades.
"We have lost one of FC Bayern's true greats, a personal supporter and friend."
