Billy Gilmour's future at Brighton could be in limbo following Graham Potter's appointment as Chelsea manager last week.
The Scotland international completed a £9million move to the AMEX stadium on deadline day after finding game time hard to find at Stamford Bridge and being initially left without a squad number.
Despite Gilmour's descent down the pecking order under the German, he was later handed the No 35 shirt for Chelsea's trip to Southampton on August 30.
Brighton had already tabled an offer for the Scot and Tuchel encouraged him to go and work under Potter to aid his career development.
