Portugal midfielder Custodio paid tribute to his side's supporters as the Euro 2012 semi-finalists continue their bid to win a first international title.
Paulo Bento's men became the first side to enter the last four on Thursday evening, sealing their place with a 1-0 win over Czech Republic thanks to Cristiano Ronaldo's header. The Seleccao will move on to face the winner of Saturday's clash between France and Spain.
Speaking after the Portuguese victory, Braga star Custodio revealed that for him the most important part of the team's success was making their loyal fans proud.
"The key was to win and secure that place in the semi-finals. We are all happy with that, the Portuguese people must also be proud and that for us is vital," he explained.
"The humility, team spirit, talent and quality is enormous [in this side]".
The 29-year-old former Dynamo Moscow man is a new addition to the Portugal squad, having made his debut during a defeat to Turkey in June, and has accrued three international caps.
