The Mirror reports that the 23-year-old is set to become Hughes’ first signing at Fulham.
Halliche is set to have a trial at Fulham before completing a £1.8million move to the PRemier League side.
He said: “I am a Benfica player but I am leaving and I haven’t yet signed for another club. I turned down Guimaraes because I think I will have better offers before the end of the transfer window.
“As for Fulham, Arsenal and all the other clubs mentioned, all I can say for now is that there is nothing finalised.”
