The Braga star was in inspired form as his side snatched a last-gasp friendly victory on Saturday.
Portugal coach Paulo Bento hailed goalkeeper Eduardo after his team's 1-0 win against Mexico in its pre-World Cup friendly.
Eduardo made four crucial saves at Gillette Stadium in Massachusetts on Friday before Bruno Alves scored the only goal of the game to give Portugal victory in stoppage time.
Bento described the Braga star as "fantastic", while also expressing his pleasure with his team's "effort" and "attitude".
"I think we were more forceful and we had the best opportunities during (the first half)," the 44-year-old coach told RTP. "Early in the second half was balanced with an opportunity for each side, and then, thanks to some fatigue, Mexico claimed two more opportunities, and great merit to Eduardo, who had a fantastic game.
"I want to underline the effort we have been making and the attitude we have shown in our work."
Eduardo spoke of his gratitude for the way he has been supported by Bento and his teammates since the beginning of Portugal's World Cup training camp.
"For me it's always an honor and a great feeling to wear this shirt and be able to represent my country," he said. "So, I always try to do my work and repay the trust they have placed in me after a difficult year.
"We won, which was the most important. From the first day I am available to complete to help the group. We are working step by step."
