1990 World Cup winner Frank Mill passed away on Tuesday following a severe heart attack.
This was confirmed by Mill's former clubs Fortuna Dusseldorf and Rot-Weiss Essen.
Mill was 67 years old and is survived by two biological children.
According to Bild, Mill suffered a heart attack support in May and was resuscitated by emergency doctors.
"Our thoughts are with Frank's family and all those who were close to him," said Dusseldorf's press release.
"Frank was not only one of the greatest footballers Rot-Weiss Essen has ever produced - he was also a fine person: down-to-earth, authentic and full of positive energy," said RW Essen's board member Alexander Rang.
"With his manner, he not only shaped our club and the Ruhr region, but was also an ambassador for football throughout Germany.
We are very sad.
With Frank, we are losing a red-white legend - and a true friend of the RWE family.
His achievements will remain unforgotten.
They are a role model and an obligation for us.
"Mill was part of West Germany's 1990 World Cup-winning squad, which has now lost its second member after Andreas Brehme, who passed away in 2024.
Mill played for Dusseldorf, Essen, Borussia Dortmund and Borussia Monchengladbach.
He made 17 appearances for the national team, but did not play at the 1990 World Cup.
