The Israeli has dismissed recent reports linking him with an assistant role under new boss Rafa Benitez, insisting that the interim coach must be given the club's full support.
The former Blues boss, who guided the club to the UEFA Champions League final in 2008, has been linked with a return to the Stamford Bridge dugout in recent weeks after Benitez's less-than-auspicious start at the club, although the club has denied the reports.
The 57-year-old Grant has dispelled the notion he could be set to take the reins at the 2011-12 European champions, though, adding that the club ought to get behind Benitez as they seek to challenge for honors this season.
"Nobody from Chelsea has offered me this job. I heard a rumor, but I think this is not what's important," Grant told BBC Radio 5 Live. "What's important is Chelsea have a manager, and the club need to support him and not look for any other things.
After Grant was fired by Chelsea owner Roman Abramovich following the Blues' run to the Champions League final, he had stints at Portsmouth, West Ham and Partizan Belgrade but is currently without a club.
"I don't think it's the right idea for the moment. I don't like to speak about myself now, because I have other things to do at this stage," Grant said. "I think Benitez is a very experienced coach and manager, and I don't think a few weeks after they give him the job he will leave, and I don't think it will be right.
"He needs to use all experience to take the club in a different direction and they need to do everything to support him and not to look around."
