Former Washington Diplomats defender-midfielder Wim Jansen, who played in two World Cup finals for the Netherlands, passed away on Tuesday.

He was 75.

Jansen had been living with dementia.

Feyenoord, the club at which he forced his reputation, said Jansen was “an icon and child of the club.”

“Everyone at #CelticFC was saddened to hear of the sad passing of former manager Wim Jansen this morning at the age of 75.

“Rest in Peace Wim, You’ll Never Walk Alone,” Celtic said on Twitter.

A Dutch international who played most of his career with Feyenoord in the Netherlands, Jansen also managed the team for three years, winning the Dutch Cup twice. He had several other roles with the club, including youth coach, assistant coach and technical advisor.

He played for Feyenoord from 1965-80, winning the 1970 European Cup final over Celtic, before venturing across the Atlantic Ocean to play for the Dips. He made 56 appearances during the 1980 and 1981 seasons before completing his career with Ajax in his native country in the 1981-82 campaign.

Born on Oct. 28, 1946, Jansen represented the Dutch 65 times. He played in the 1974 and 1978 World Cup finals for the Netherlands, which finished second in both competitions.

Jansen won four titles with Feyenoord and the 1974 UEFA Cup. He also won another championship with Ajax.

In his lone season as Celtic manager in 1997-98, he directed the club to the Scottish Premiership title, snapping archrival Rangers’ nine-year hold on the championship.
