The player was signed by Gerard Houllier, but spent last season on loan at French second division side Lorient.
But despite featuring in two pre-season friendlies, Medjani is unsure of where his future will lie next year.
He said: "I will know my future in the coming days. Rafael Benitez told me we will soon have a talk. I will know if he relies on me for next season. If not, I will see with my agent if a loan is possible. Lorient wanted to keep me. Why not go back?"
