Atletico Madrid's Portuguese midfielder Tiago announced on Monday that he is retiring from international football.
"The time has come to call time on this fantastic experience," Tiago wrote in a letter made public by the Portuguese football federation.
The 29-year-old said that he was making the decision "for personal reasons" and to allow "new Portuguese footballing values to find their place."
Tiago, who has 58 caps for the national side, made his international debut against Scotland in 2002 and has scored three goals. The former Chelsea, Benfica and Lyon player is currently on loan with Primeral Liga club Atletico from Serie A side Juventus.
