Guus Hiddink has been approached by Manchester City, according to the Russia manager’s agent.

Cees van Nieuwenhuizen has said he was contacted by City chief executive Garry Cook to request talks with Hiddink, but the former Chelsea boss’ agent politely declined.

"Yes, I did (speak to Cook). But Guus is happy with Russia. Definitely," Van Nieuwenhuizen told the Daily Telegraph.

Van Nieuwenhuizen is not aware whether Cook wanted to discuss the possibility of Cook succeeding manager Mark Hughes or being installed alongside the Welshman.

“I don’t know because I said it was not worth discussing it because Guus was happy,” he said. “I had a call because I have been working with Garry for 12 years since we worked together at Nike.

“He (Cook) asked me if it would be worthwhile having a meeting to discuss the future and what might happen next summer. But I told him that Guus was contracted to Russia.

“I said I didn’t think it was worth having a meeting. Guus is very relaxed. He starts his holiday tomorrow and in January there are elections for a new president for the Russian Federation.

“He is contracted until next summer but there is an offer for him to stay for two more years, and I think he will definitely stay.”

Pressure is mounting on Hughes following six wins in City’s opening 16 Premier League matches this season, which leaves them eighth in the table.

Van Nieuwenhuizen expects Hiddink to remain with Russia beyond his current deal, which expires next summer.

City are not the only club to express an interest in Hiddink.

Van Nieuwenhuizen added: “I have received calls from all over the world about Guus. There has also been an approach from Juventus.”
