Da Silva is set to join the Portuguese side on loan for a season.
His agent Cassiano Pereira said on Monday: “There is a high possibility that Fabio will go to Benfica.
“Alex Ferguson has talked with me and Fabio about this possibility and the next two or three weeks we should know our position.”
United boss Sir Alex Ferguson has previously confirmed that Fabio will go out on loan next season.
Ferguson told United Review: “Fabio will go on loan next season to give him concentrated first-team experience.
“I have already talked to him and he understands the value of playing regularly at a higher level than we can give him at the moment.”
