Simons has expressed his willingness to leave RB Leipzig, as evident from his decision to remove the club's logo from his social media profile.
According to sources, Chelsea and RB Leipzig are close to agreeing on a transfer fee, but a formal bid has not been made yet.
Before a deal can be finalized, Chelsea must first complete the sale of a player, as RB Leipzig values Simons at a price range of €60-70 million.
