Thomas Tuchel has called for clarity and a swift resolution to Chelsea's ownership situation.
There were further developments on Thursday which marked the deadline for improved and final offers from the three parties wanting to buy the club from Roman Abramovich.
It came as the consortium led by the Ricketts family withdrew from the process.
Meanwhile, Chelsea director Eugene Tenenbaum – viewed as Abramovich's right-hand man – has now also been sanctioned by the UK government along with the outgoing Blues owner.
