Tributes have been paid to Freiburg president Achim Stocker, who died on Sunday.

Stocker was the Bundesliga's longest serving president, having led the club from the Black Forest for the last 37 years.

The 74-year-old suffered a heart attack on Wednesday and passed away just before Freiburg played Hoffenheim yesterday, a game they lost 1-0.

"Achim Stocker will always remain in our hearts," a club statement read.

Hoffenheim coach Ralf Rangnick added: "His death overshadows this game. He was such a lovely man."
