Born in Lomma, Scania, Ljung started his football career at the age of six, with lowly Lunds BK. In 1985 he was purchased by Allsvenskan outfit Malmö FF, being mostly used as a substitute in his early years and being on the roster as the club won five national championships in a row, with the player contributing regularly in the 1987 and 1988 editions.
In the summer of 1989 Ljung transferred to BSC Young Boys in Switzerland, moving in the following season to another club in the Swiss Super League, FC Zürich. He enjoyed his best individual years in Austria with FC Admira Wacker, scoring 26 Bundesliga goals in 67 games in his first two years combined, albeit without team silverware.
In 1994, after some months in Turkey with Galatasaray SK, Ljung transferred to MSV Duisburg in Germany. After appearing in less of half of the games during the campaign and also suffering relegation from the Bundesliga, he decided to retire from football at only 29.
Ljung was also selected for the team in UEFA Euro 1992, played on home soil: his contribution to the final third-place was again minimal, as he only featured in the 2–3 semifinal loss against Germany.
In the 1994 World Cup in the United States, Ljung opened the national team's scoring account in a 2–2 group stage draw against Cameroon. This time, he was an undisputed starter for the side – playing in six of seven games – whom eventually finished third.
After retiring from professional football in 1995, Ljung became a sports agent. He started his own agency in Lomma, Roger Ljung Promotion AB, being at the time one of only three licensed agents in the country; newspaper Aftonbladet considered him to be Sweden's most successful agent.
Ljung's most notable client was Fredrik Ljungberg, who played several years in the Premier League. He brokered his deal with Arsenal for a £3 million transfer fee, and the pair parted ways in December 2006 when the player signed with mega-agency Creative Artists.
