Someone get to the airport and see who is on that jet from Dusseldorf, really clutching at straws today, doesn't look like much is going to happen...
Given the track record of jets I imagine it’s a rich German businessman. Or, at a push, a rich businessman of other descent returning from business in Germany.
Just to give you a heads up - by the time a player is boarding a jet the fee is agreed and the selling club and the agent has told someone like Fabrizio Romano.
