Russia manager Guus Hiddink will never make a return to club management despite reports linking him with Chelsea, his agent has revealed.
Van Nieuwenhuizen told BBC Sport: "There is no chance of Guus going to Chelsea. He wants to end his career in international management.
"He signed a new deal in March that runs up to the 2010 World Cup and always honours his contracts."
Grant has largely surpassed expectations since taking over from the popular Jose Mourinho and two wins in the next week, albeit against Liverpool and Manchester United, would see the Blues with one hand on a place in the Champions League final and a renewed chance of wresting the Premier League title from the Red Devils' grasp.
But the 61-year-old's representative Van Nieuwenhuizen was unequivocal in distancing him from the club.
"I don't know where these stories about Guus come from and I want to put an end to them once and for all," he added.
"It isn't about money for Guus. It's about him having signed a contract and wanting to get on with his job with Russia."
