He was a talented midfield player who won three European Cup titles with Ajax Amsterdam in the early 1970s, after having started his career at FC Volendam. He played for Ajax Amsterdam between 1968 and 1976. He later played for Real Betis and Seiko in Hong Kong. He was capped by Holland for 10 games. According to David Winner, author of ‘Brilliant Orange’ the greatest moment of Ajax’s ‘Golden Age’ was not a goal or a great save. It was a simple piece of juggling by a player who had idolised the legends which had graced the turf of the Bernabeu before him. Gerrie Muhren had the 110,000 fans applauding, rather than the customary white handkerchiefs away teams were used to. It was said to be the moment Ajax took over from Real Madrid as the true Kings of Europe. Having already won the two previous European cups, Ajax strolled to their third successive European Cup victory, having raised the Bernabeu to applaud the brilliance of totaalvoetbal.
His younger brother, Arnold Mühren, was also a notable football player for Holland, Ipswich Town, Manchester United and Ajax Amsterdam.
