Everton FC left-back Nuno Valente has announced his retirement from international football despite the Portuguese Football Federation registering him to play 2010 FIFA World Cup matches. Valente, who won 32 caps and featured prominently in Portugal's run to the World Cup semi-finals in Germany two summers ago, said: "I was very pleased to receive a provisional call-up, but I feel I've done my job and I'm not capable of representing my country as a player should." The 34-year-old, a UEFA Champions League winner with FC Porto, recently signed a 12-month contract extension with Everton.
