Despite winning Chelsea’s Player of the Year award for the last two seasons, Mata’s abilities are clearly not rated by returning manager Jose Mourinho.
The divisive Portuguese tactician has started him for just one out of four games so far this season and left him as an unused substitute in the other three.
That kind of snub has put some of the continent’s biggest clubs on red alert.
Paris Saint-Germain are ready to open negotiations with the Stamford Bridge club over bringing Mata to the French capital, and according to French television station Infosport Plus they have already spoken to Mata himself.
Given that they already trail Monaco by two points in France’s Ligue 1 and have been held to two draws in four games, they could really do with the Spaniard’s wizardry.
No player has registered more assists in the past two Premier League seasons than Mata and his creative nous, clearly unneeded by Chelsea, will be a huge draw to the French side.
The current £35m playmaker Javier Pastore, bought two years ago from Palermo, has failed to live up to expectations and has been booed in home games this season.
The filthy rich Parisians may well have to contend with the pulling power of Manchester United though, as the English champions move to inject some ingenuity into a side that has gone goalless against two huge rivals in the last two games.
Mata was originally discussed as part of the package in a potential Wayne Rooney deal earlier in the window, and although that move seems dead in the water he could still be the subject of an eleventh hour Red Devils bid.
It seems Mata’s suitors are plentiful as the window draws to a close, with Liverpool – 11/1 shots to win the league – reportedly rebuffed on a £30m bid for him.
Brendan Rodgers has made serious moves to strengthen his squad this summer and a successful pursuit of Mata would make the former Valencia man the ninth new Anfield arrival since the end of last season.
