The Manchester United star was selecting some of the best players he has ever played with.
And pinning his international colours to the mast, the 26-year-old may spot Michael Carrick with a sulk on around Carrington after naming two former Spanish teammates as the best passers he has shared a pitch with.
The three won the 2010 World Cup and 2012 European Championships together for Spain, and it would be hard to argue against the hero of United's recent 2-0 win over Liverpool with his selection.
Turning to the best finishers he has ever played with or against, Mata stuck a little closer to his club with his selections.
The Spaniard chose Robin van Persie and David Villa as the finest goalscorers he has ever played with, with the Dutchman clearly impressing the ex Chelsea man in his short spell at the club. Van Persie has had an injury interrupted couple of seasons, but has still managed to register 57 goals in 101 games, better than one in two.
Mata went for fellow United striker Radamel Falcao for best finisher he's ever played against, and surely must have had in mind the Colombian's impressive hat trick for Atletico Madrid against Chelsea in the 2012 Super Cup. Falcao scored three times in the first half to really underline his quality at the highest level, and it is a game worth keeping in mind for those that doubt the South American star's goalscoring ability. He just has to find it again.
