In another winter transfer window, Dimas left Fenerbahçe in 2000 and played six months at Standard Liège. After a good run at UEFA Euro 2000 with Portugal (he made his first international appearance in 1995 while at Benfica, and was the nation's first choice at that and the previous continental competition, playing four games in each), he proved he could still be of value for a title contending team, and returned home after signing for Sporting CP.
