According to the Times, Paris Saint-Germain are expecting Chelsea to submit an offer for Kylian Mbappe next week.
Paris Saint-Germain are also expecting offers for Mbappe from Saudi clubs.
PSG are attempting to force a sale of Mbappe in the present window after the forward opted against signing a new PSG contract.
PSG are reportedly open to accepting a fee of €100 million (£86.6 million) for the 24-year-old France captain who has one left on his PSG contract.
PSG signed Mbappe from Monaco for €180 million in 2017, a record for a teenager and still the second-highest transfer fee for any footballer.
