Club president Nasser Al-Khelaifi has urged Real Madrid to show PSG respect amid repeated links with Kylian Mbappe and Neymar.
Reports from French outlet Le10 Sport earlier in the week suggested Neymar and Real Madrid had struck an agreement in principle to secure a shock return to LaLiga for the Brazil star.
Meanwhile, Los Blancos have also been linked with a mega-money move for Neymar’s PSG team-mate Mbappe, but Al-Khelaifi has told Real to remain professional.
He told Marca: “It’s a bit frustrating if we’re being realistic because it’s not fair for other clubs or anyone to speak with our players.
“We don’t like it at all and we spoke about it with Real Madrid at one moment. We have a good relationship with them and they respect PSG, and I hope that this is true.
“We respect Real Madrid and their president Florentino Perez. I think it’s important for everyone that we don’t work behind the scenes.
“If there is something there then it’s better that we speak, whether that’s speaking with Florentino Perez or whoever and then saying what we like and what we don’t like. That’s what we expect of all clubs, not only Real Madrid.”
He added: “Mbappe is already one of the best players in the world. As is Neymar. To be honest, I see them as the best two players in the world.
“Of course, we have the best forwards. There’s also [Edinson] Cavani and [Angel] Di Maria and it’s a matter of pride.
“The good thing is that this allows you to think in a long-term project. We’ll go out to try to win each title and we’ll fight because we are obligated to.”
