Neymar has been on Perez’s radar ever since he broke on to the scene in Brazil with Santos.
And Real were given a sniff of one day signing him when he left their arch-rivals Barcelona last summer.
Neymar’s stint at PSG has been surrounded by speculation he will be offered a route back to La Liga at the end of the season.
And the latest reports from Spain suggest Perez is doing his due diligence ahead of a potential world-record deal being completed.
According to Sport, Real are unconcerned by the finances required to prise Neymar away from PSG.
However, they are worried about the influence he may have on team-mates and vice versa.
Real are apparently also looking into Neymar’s father, due to his influence on his son’s career.
The 26-year-old’s father was instrumental in his move to PSG that led to bad blood with Barcelona chiefs.

Real are also investigating Neymar’s nights out, which have seen unflattering pictures supposedly unbefitting of a sportsman circulated before.
Perez’s exploration into Neymar away from the field comes amid concerns he could mirror Ronaldinho.
The Brazilian legend was one of the world’s best players but went off the rails towards the end of his time at the Nou Camp.
And Perez hopes Neymar is more likely to follow in Cristiano Ronaldo and Lionel Messi’s footsteps instead by being a consummate professional.
