Chelsea ace Mata scoffs at burnout fears ahead of game No59
He will step out for his 59th outing of the campaign when Spain kick off against Japan in Glasgow next Thursday.
And he insisted: "We're not just looking for a magic moment. We want to win gold to show there is no doubt that Spain are the best soccer nation in the world.
"I'm dreaming of a gold medal to complete my incredible first season in England. I never believed that I could win so many titles in just a few months. I am very happy.
"There has been no pressure from Chelsea about playing at the Olympics.
"I spoke with them some months ago about playing at the Euros and then the Games and I don't believe the extra effort will be a negative for the start of the Premier League season.
"It won't be a problem. It's going be very tense but we must challenge for the title."
