Former Celtic manager Wim Jansen has passed away aged 75.
His death has been confirmed by Feyenoord who have paid their respects to "a wonderful person and great Feyenoord player".
Jansen only spent one season in Glasgow but is famed for stopping Rangers winning 10 in a Row in 1998.
He worked with Henrik Larsson at Feyenoord and brought the legendary Swede with him to Glasgow in 1997.
Jansen confirmed in October last year that he had been living with dementia shortly before his 75th birthday.
Feyenoord have now confirmed his passing in a short statement which reads: "A wonderful person and great Feyenoord player is no more.
"Wim Jansen, rest in peace…"
Jansen prevented Rangers from winning a tenth title in a row as his side finished two points ahead of Walter Smith's Gers in 1997/98.
Differences with Celtic general manager Jock Brown meant Jansen's tenure only lasted one year, but he made his mark and is a revered figure at Parkhead.
He introduced Larsson to Scottish football and laid the groundwork for the sustained success that would follow under Martin O'Neill and Gordon Strachan.
Jansen was once described by the legendary Johan Cruyff as "one of only four men in the world worth listening to when they talk about football," such was his mark on the Dutch game.
He won five league titles with Feyenoord and Ajax as a player and went on to win two cups with the former as manager.
