Real Madrid have regularly been linked with a move for Neymar, although statements from the club have denied that a few times, while talk of Barca's interest in re-signing the 26-year-old has gained traction this week.
Neymar, 26, is within his second season with the Ligue 1 champions since making a world-record €222 million from Barca but is said to be considering his options.
However Marquinhos sees it very differently and says it won't be easy for Barça or Real Madrid to lure Neymar away from PSG next summer.
The reports come as speculation mounts regarding Neymar's future in Paris and amid rumours of dissatisfaction at the club.

The deal "will allow us to intervene to rebalance the market in any appropriate time from January onward", he said. The Saudis have laid out different versions of the circumstances that led to Khashoggi's.
That does not mean he can not leave earlier, just that a club would have to haggle with PSG if they wanted to sign him and it would probably be for a fee greater than his 2020 release clause.
He suggested that Barcelona would not be able to put together enough cash together to sign Neymar, even if they sold Ousmane Dembélé.
Neymar joined Barcelona in 2013 scoring 105 goals and notched up 77 assists in 186 appearances before moving to PSG in the summer of 2017.
