Thijssen started his professional career in 1970 with
NEC Nijmegen. In 1973, he moved to
FC Twente, where he played for nearly six seasons. In 1979, Thijssen moved to England to sign for
Ipswich Town joining former FC Twente teammate
Arnold Mühren. In 1981 he was the first Dutchman to be voted
English Footballer of the Year as he helped Ipswich Town win the
UEFA Cup, scoring one goal in each of the two legs of the final. He played a big part in their run to the semi-finals of the
FA Cup, and they also finished second in the league that season. He helped them finish second again the following year, but a year later he departed from
Portman Road after four years to sign for
Brian Clough's
Nottingham Forest, but he was not nearly as successful at the
City Ground as he had been in
East Anglia, and he had left the club within months. He also had a stint in the
NASL with the
Vancouver Whitecaps. In 1984, he returned to his native country, to play for
Fortuna Sittard (1984–1987),
FC Groningen (1987–1988) and
Vitesse Arnhem (1988–1991). ==Managerial career==
