Career
Mužinić spent most of his career in his native Yugoslavia. He was named the Yugoslav Football player of the Year in 1977. Norwich City manager John Bond signed him in 1980, paying what was then a club record £300,000 for his services.
However, his time at Norwich was not a success.
He struggled for form and did not speak English, making communication at times impossible. At one match, Bond employed the services of an interpreter from the University of East Anglia to pass on instructions to Mužinić from the touchline.
Mužinić made just 23 appearances for Norwich, 17 starts and 6 substitute appearances. He did not score a goal for the club
He made his debut on 13 September 1980 and his final appearance for the club came on 28 December 1982.
By then, Bond had left the club to manage Manchester City and his successor Ken Brown cancelled the player"s contract at the end of the 1981-1982 season. Bond admitted that he had not seen Mužinić play and had signed him on reputation, leading then-Norwich player Justin Fashanu to say "I don"t think we got Muzinic, I reckon they sent his milkman."
In his 2002 updated edition of Canary Citizens, Mike Davage reported that Mužinić has been running a restaurant in Brač. He has also worked as a scout for his former club Hajduk Split.
