According to one bookmaker, Forest (6/1) are one of the main contenders for Toure's signature, behind any Chinese (2/1) and MLS club (5/2).
But how likely is it? HITC takes a look...
Why's he left Olympiacos?
The official reason is unclear, although financial reasons have been cited (Sky Sports). We do, however, know he left on good terms, after the Greek side said in a statement: "Yaya is and remains an important member of the Olympiacos family (one which now includes Nottingham Forest after the club's purchase by Evangelos Marinakis) who has marked a central part of the history of the club.
"Yaya will remain deeply devoted to the club and wishes to Olympiacos lots of success.
"Yaya is leaving as a friend and the doors at Olympiacos will always be open for him.
"Our paths will surely cross again."
What has Toure said?
Nothing yet, but he is said to be eyeing a return to English football - specifically the Premier League (Sky Sports). Two clubs, West Ham United and Crystal Palace, have already distance themselves from the 35-year-old.
Do Nottingham Forest need him?
In short, no. Aitor Karanka's central midfield options currently comprise eight players - Adlene Guedioura, Jack Colback, Ben Watson, Joao Carvalho, Panagiotis Tachtsidis, Liam Bridcutt, Claudio Yacob and Ryan Yates. Although, a player of Toure's quality could significantly boost the Reds' promotion charge.
Verdict: Stranger things have happened - but maybe spend your money elsewhere on this occasion.
