Tragically, Germany and Bayern Munich icon Gerd Muller has been diagnosed with Alzheimer's disease - a form of dementia that affects memory, thinking and behaviour.
The 69-year-old will forever be famous not only for his playing time at Bayern, for whom he scored an incredible 398 goals in 453 appearances, but also for his country, practically dragging West Germany to the 1974 World Cup trophy and bagging 68 goals in 62 caps.
Possessing a unique playing style, similar to that of Sergio Aguero or Lionel Messi, his low centre of gravity equipped with an eye for goal and poaching instincts put Muller up there with some of the best strikers of all time.
Along with his World Cup winners medal, he won trophies galore with his beloved Bavarians, including three European Cups and four Bundesliga titles over the course of his 15-year career in Munich.
Nicknamed 'Der Bomber', Muller was truly special and gifted individual, and one that has deservedly received the acclaim that he has done even in the years surpassing his retirement.
