Reports have suggested that the midfielder may be moved on this summer as incoming Blues boss Andre Villas-Boas attempts to stamp his authority on the Stamford Bridge squad.
Speculation regarding the Ghanaian's future has alerted some of Europe's top clubs to his possible availability, with AC Milan and Bayern Munich waiting to pounce.
It was claimed that Bayern were ready to test Chelsea's resolve with a formal offer, with it unclear where Essien fits into Villas-Boas' thoughts.
His representative insists there is nothing in the rumours, though, with the 28-year-old still very much part of the Blues' plans for the upcoming campaign.
Fabien Piveteau told MTNFootball.com: "There's absolutely no chance of Essien leaving Chelsea.
"It is not true that the club's new coach Villas-Boas wants to release Michael.
"In fact, the new coach knows Essien very well having worked at the club before and he knows what Michael can do for the club.
"Michael is also focused on staying at the club because he has a very good relationship with the team's supporters, the new manager and the club owner.
"He is not leaving."
Villas-Boas was part of Jose Mourinho's coaching team at Chelsea when Essien was snapped up for ?24million from Lyon in the summer of 2005.
