The Chelsea ace was delighted to score a goal in the final and hailed La Roja's performance in Kiev as he hopes his country can extend their glory era in Brazil 2014
"Now it is time to enjoy but hopefully we can repeat this [triumph] in Brazil," Mata told Goal.com.
The 24-year-old came off the bench to score Spain's last goal of the match in what was his first and only appearance for La Roja in the tournament.
David Silva and Jordi Alba had opened the scoring in the first half, before Cesare Prandelli's men were forced to play the final 33 minutes with 10 men after Thiago Motta had to be stretchered off injured without any further substitutions available.
Mata then followed up Fernando Torres' strike to round off a superb victory - prompting scenes of huge celebration.
And the Chelsea playmaker was delighted that he was able to play his part in Spain's third tournament victory in a row - but insisted he and La Roja were not finished there.
"I cannot explain how happy I am for winning the Euros and scoring a goal in the final, I cannot ask for anything more," Mata stated. "We are particularly pleased because we played really well and scored many goals, which is unusual in a final. We also benefited that they went one man down after Thiago Motta's injury, but we were great in general."
He added, "It is easier for us to play against a team like Italy, who try to play attacking football and leave more spaces. It makes the games more attractive and suits our style."
Despite Spain's crushing 4-0 victory over Italy, Mata explained that winning Euro 2012 had its challenges and there were times during the tournament where things appeared uncertain.
"We always knew it would be very difficult to win the Euros. I cannot say that we doubted ourselves, but sometimes you think that teams can find the formula to beat you," he said. "Fortunately, this was not the case and here we are again, celebrating."
