PSG are now also reported to be in the race for Mata following the appointment of Unai Emery as head coach according to Le 10 Sport.
Emery knows Mata well from his time coaching La Liga outfit Valencia and is reported to be keen on being reunited with his former pupil.
Mata faces an uncertain future at United following the appointment of Jose Mourinho as head coach.
Mourinho famously got rid of Mata after taking over Chelsea and there are fears he could do the same at Old Trafford.
The Mirror does however, report that Mourinho is willing to give Mata a chance to prove himself at United.
The Istanbul giants would be able to offer Mata first team and Champions League football were he to make the move.
