AS Monaco vice-president Vadim Vasilyev has announced they're willing to sell Fabinho this summer.
The Brazil international has courted interest from Atletico Madrid, Manchester United, Manchester City and PSG this season.
"We owe it to the kid, he has been in this house for four years and we promised him," said Vasilyev.
"We have to wait for the right offer and we will never let a player go without a good offer."
He added: "Atlético is not the only club that has shown interest."
