Christofte was a part of the Brøndby team that won the first Danish League in club history, and made his national team debut in September 1984. Having played four national team games, an injury stopped him from competing at the 1986 FIFA World Cup in Mexico. He once again moved abroad to play for Spanish club CD Málaga and Switzerland's FC Wettingen, but his stays at the clubs were unsuccessful, and for the next seven years he was absent from the national side, under legendary coach Sepp Piontek. He moved back to Denmark to play for Odense Boldklub in 1987, returning to Brøndby the following year.
