Mata’s involvement is not a surprise after he agreed his commitment to Spain’s Olympic plans with Chelsea earlier this summer:
“I have confirmed with Chelsea that I can play the Olympics” said Mata.
“It’s something I have agreed with the Spanish federation, and I don’t want to change.
“My dream is to play and win the gold in London. After winning a lot with Chelsea last season, that would be another great honour.”
After celebrating Spain;s triumph in Madrid on Monday in front of thousands of fans, Mata and Alba will have just four days rest before linking up with his 2012 team-mates.
Spain host Senegal in Gran Canaria on July 13 before playing Mexico in Cadiz on July 18. The gold medal favourites open their Olympics campaign in Glasgow on July 26 against Japan at Hampen Park before Group D games against Honduras in Newcastle and Morocco in Manchester.
