The 34-year-old has praised Portugal coach Paulo Bento who has guided the Euro 2004 runners-up to the semi-finals, and he thinks they can go all of the way this yearFormer Chelsea manager Andre Villas-Boas believes Portugal can win Euro 2012 after they progressed to the semi-finals.
Cristiano Ronaldo's header gave the Seleccao the vital goal in their 1-0 quarter-final win against Czech Republic, and they now face the possibility of playing Spain or France in their semi-final.
Portugal, who began the tournament badly with a 1-0 defeat to fellow semi-finalists Germany, have now won three consecutive games including the 2-1 defeat of Holland.
And Villas-Boas feels that Portugal's boss Paulo Bento is doing a great job.
"There has been an evolution after every match. Portugal have the right coach," Villas-Boas told reporters.
"Yesterday, we took another decisive step and we have every chance to win the tournament."
Villas-Boas, meanwhile, has been heavily linked with the vacant managerial position at Tottenham after Harry Redknapp was sacked by chairman Daniel Levy.
