Paris Saint-Germain would block any potential return to Barcelona and Real Madrid for Lionel Messi and Sergio Ramos, according to Marca.
There are speculations that both players are seeking a return to their former sides.
Both Messi and Ramos have endured a difficult first season in Ligue 1 after moving from Spain.
Messi has been the target of fans’ anger following their Champions League exit in the hands of Real Madrid. He was recently booed along with teammate Neymar in a league fixture against Bordeaux.
Ramos on his own part has been struggling with several niggling injuries and has barely featured.
However, PSG see both players as crown jewels among their squad and would hate to let them go.
