Olympiakos are confident of closing a deal for Yaya Toure this week.
Sky Sports says negotiations are continuing between Olympiakos and Toure, following his release from Manchester City this summer.
No deal has been concluded yet but an agreement is close and should be completed before Friday's transfer window closes in Greece at 11pm local time.
The 35-year-old made 20 appearances for the Greek outfit back in 2005 and is set to secure a move to the Karaiskakis Stadium after being released by City this summer.
