Discussions between Chelsea and RB Leipzig are ongoing to determine a suitable transfer fee for the Dutch international player.
Simons has expressed his willingness to leave RB Leipzig, as evident from his removal of the club's logo from his social media profile.
Although verbal agreements have been reached between the two clubs, a formal bid has not yet been submitted.
Chelsea must first complete the sale of another player before they can finalize the transfer of Simons, who is valued at €60-70 million by his current club.
