AS Monaco are waiting on a call from Manchester United this week over Fabinho.
Le 10 Sport says ASM expect to make one big sale before the transfer deadline, with either Fabinho to United or Bruno Silva to Real Madrid the options on the table.
United boss Jose Mourinho is a big fan of Fabinho and keen on a deal.
But nothing will happen unless Matteo Darmian agrees to leave Old Trafford in the coming days.
If the Italian is sold, United will immediately bid for Fabinho, who is well aware of the situation as he shares with Mourinho the same agent, Jorge Mendes.
