9. Nikola Jovanovic
Known well in his home country as one of the great players back in the 1970’s when he played for Belgrade. He played 359 games and managed to score an impressive 50 goals as a defender. History was made when the footballer moved to Manchester United, becoming the first Yogoslav footballer to play for the Red Devils. Despite his big money move, Nikola Jovanovic’s performance at United was really poor and most would say, he turned out to be one of the top-5 worst defenders ever to play for Manchester United.Â
