Senna recovered from a shaky start to put in an imperious performance against Germany at the Euro 2008 final in Vienna.
"We deserved to win," he told Europa Press.
"This is the happiest moment of my footballing life. I'm very glad to have won and I can't wait to celebrate with everyone."
His Villarreal teammate Santiago 'Santi' Cazorla came on as a second-half substitute.
The young winger added, "It's a unique, historic achievement."
The former Recreativo man's bit-part status was no concern for him.
"I came here to help and to work hard. I had confidence in myself and things had gone well," he concluded.
