Sven-Goran Eriksson has compared Yaya Toure to Zlatan Ibrahimovic by claiming that the veteran midfielder would not sign for a club unless he was sure that he could do the job.
The Swede managed Toure, a free agent after leaving Manchester City at the end of last season, while in charge of Ivory Coast in 2010.
Dimitry Seluk, the 35-year-old's agent, tweeted a cryptic message on Tuesday night claiming that Toure has passed a medical in London, though the identity of the club is unknown.
"He's a very proud man, and he's proud of what he can do," the former England boss told Sky Sports News. "I don't think we would sign for any club knowing he can't do the job.
"He is a little bit like Zlatan, they are great players and they know what they have done, and they know today what they can do.
"So, Zlatan said no to Sweden [for the World Cup], I think because a tournament, a game every third or fourth day, no. I think that was very good for him. On the other hand, he can do it in the United States, he knew that.
"If Yaya decides to play in London, England or China or wherever, he surely can do it. Yaya is a great player, great head, great feet."
Toure won three Premier League titles, three EFL Cups and an FA Cup across 315 appearances for City, scoring 79 goals, since signing from Barcelona eight years ago.
