The younger brother of another footballer, Klaus Allofs, he was a prolific goalscorer, having scored nearly 200 overall goals as a professional, always playing in the Bundesliga (a brief spell in France notwithstanding).
Born in Düsseldorf, Allofs started his professional career aged 19, netting five goals in 17 contests with local giants Fortuna Düsseldorf. In his first year, he combined with sibling Klaus for 29 team goals (out of 70, league's third-best), as Fortuna finished seventh; he also played in five matches in the club's UEFA Cup Winners' Cup runner-up run, including the extra time final loss against FC Barcelona.
In 1982, Allofs joined 1. FC Kaiserslautern, where he proceeded to score at an impressive rate (an average of 15 per season), although the team did not win any silverware. Subsequently, he moved to 1. FC Köln, rejoining with his brother in 1986–87, and being crowned the league's top scorer in his third season, with the team finishing second.
Allofs was an uncapped (an unused) member for West Germany in the 1982 FIFA World Cup campaign, which ended with runner-up honours. He would receive two caps during three years, the first coming on 16 October 1985 in a 1–0 defeat in Stuttgart against Portugal in a 1986 World Cup qualifier.
