Manchester United are battling to keep hold three of their senior players.
The Daily Star says Fabio is now considering his options.
The 23-year-old Brazilian has played just ONE game all season under David Moyes.
He's frustrated with the lack of chances and could join Nemanja Vidic and Javier Hernandez in walking out the club.
Fabio said: "I think I might leave. I want to be happy. I want to play. I want to be close to my family. I may go back to Brazil."
