Spanish goalkeeper Kepa Arrizabalaga is confident in his abilities as he takes a break from his chaotic situation at club level.
Kepa is now Chelsea's no.2 keeper after the arrival of Edouard Mendy.
The 26-year-old, who is the most expensive keeper in the world, is out of favour with Blues boss Frank Lampard.
But Kepa believes in himself and hopes to show his quality while on Spain duty.
"I've felt confidence, at ease. I think it was a good game and I'm happy with the confidence of the coach," he told Teledeporte.
"When I'm needed to help on the pitch, I try to do the best possible.
"It was a game of great intensity. [We had] more control in the first half. In the second, we found it more difficult to control Portugal's transitions. It was a good test.
"We have to be happy. We stood up today. We have to improve because we conceded a few clear chances, which you can pay for in a tournament."
