PARIS -- Paris Saint-Germain could pay more than €60m to sign Monaco midfielder Fabinho, with teammate Kylian Mbappe also keen on a move to the Parc des Princes, sources have told ESPN FC.
Fabinho has been a PSG target since Antero Henrique arrived as sporting director in June.
Sources said Monaco were preparing for the possibility that both he and Mbappe could attempt to force moves if they cannot leave amicably.
PSG, meanwhile, remain hopeful that they could sign both before the end of the window.
A Monaco source said that, since last season, Fabinho has had a gentleman's agreement that he would be granted a move if a suitable offer arrived.
A Paris source said a bid of around €45 million had been tabled by PSG once Henrique arrived -- but he was then told he could not join them.
Both sources said Fabinho had been told he could go to a foreign club but wants to join PSG.
The Brazil international has refused to attempt to force a move out of respect for the role Monaco have played in his career but has grown frustrated by the club's stance.
Sources said he believes his best chance of being part of the Brazil squad for next year's World Cup is to play alongside international teammates including Neymar at PSG.
The Paris source said that after a recent pause in communication between Henrique and Fabinho's agent, Jorge Mendes, dialogue has been reopened with the aim of reaching a swift deal.
The source added that although PSG had looked at Porto's Danilo Pereira, Fabinho remained their preferred option.
