Rimantas Klivečka[1] (born 22 April 1941) known as Ray Klivecka in the United States is a former soccer player and coach.
When Firmani was fired in 1979, Klivecka took over for the remainder of the Cosmos' North American Soccer League campaign.
The Cosmos finished in first place with a 24–6 record, but Klivecka was dismissed at the end of the season after suffering a loss to the Vancouver Whitecaps in the semifinals.
In 1980 he also was head coach and general manager for seven matches of the NASL-Franchise Rochester Lancers which quit after that season.
[4] Due in part to his success with Buffalo, in the early days of December 1984 Klivecka was re-hired as head coach of the New York Cosmos, now playing indoor soccer in the MISL, for the 1984 season, where he stayed until the bitter end in mid 1985.
