The 36-year old former Manchester United and England star is still being heavily linked with PSG and 22-year old Argentine playmaker Pastore has endorsed the possibility of a move to Parc des Princes.
"Beckham? His experience is huge because he has won titles wherever he has been in his career," he told L'Equipe.
"For us younger players, he could bring a lot. Talking to him would be a big help.
"Beckham has a presence that is very impressive. In our squad, no-one has an honours list like him or so much experience."
