The fututre of the Ivorian international became a much talked about topic after his agent Dimitry Seluk tweeted that his client had passed a medical with a club ahead of signing a deal.
Toure has been without a club since the end of June, after he was released by Man City after spending eight years in Manchester, where he won three Premier League titles.
Reports emerged linking him with a move back to Olympiakos, where he spent the 2005-06 season, but the club's manager Pedro Martins would not confirm the rumours when asked.
"I have to remain concentrated on the group of players I have and not refer to players that do not belong to our group yet" the coach said ahead of his side's Europa League play-off match against Burnley on Thursday.
