Robert Michael Rosario (born 4 March 1966 in Hammersmith) is a retired English footballer who played professionally for Norwich City, Wolverhampton Wanderers, Coventry City and Nottingham Forest before playing and coaching in the United States. He played as a forward.
As a teenager, Rosario had unsuccessful trials with Tottenham Hotspur, Brentford FC and Watford FC. He played non-league football for Harrow Borough and Hillingdon Borough. Norwich City saw potential in the tall striker and he signed for the Canaries shortly before Christmas in 1983. He made his league debut on 7 April 1984 against Watford at Carrow Road, a match that Norwich won 6–1. His first goal for the club came on 21 April 1984 in a 2–2 draw against Stoke City. However, he struggled to command a regular first team place and in the 1985–86 season had a loan spell at Wolves where he scored 1 goal in his 2 appearances.
Although Rosario was far from being a prolific goalscorer for the Canaries – he would score just 29 goals in 161 appearances for the club – he was selected for the England under-21s in April 1987 and played in a match against Turkey. Rosario would win 3 further under-21 caps but effectively ended his chances of further caps when he and his Norwich team-mate Dale Gordon broke curfew on an under-21 trip and went to a nightclub.
The highlight of Rosario's time at Carrow Road came on 9 September 1989 when the first of his two goals in a 4–4 draw against Southampton would later be voted 'Goal of the Season' by ITV. But his lack of goals meant that he was not a favourite with the Carrow Road crowd and when Coventry City manager Terry Butcher paid Norwich £600,000 for his services in March 1991 it was seen as good business by the majority of City fans.
