“Ultimately, I made my decision based on the special relationship I have with this incredible club.
“I am as hungry for success now as I was when I first arrived here many years ago and I cannot wait to help the club win the trophies the great fans of Olympiacos deserve.
“It is now time to let my football do the talking once again. Let’s do this!”
The Greek league leaders confirmed the move but did not give financial details. Local media said Toure would be paid around €2.5 million ($2.9m) for one season.
