Not sure who/what is driving their recruitment decisions. Marina Granovskaia left once the Boehly takeover became official, and from what I hear, he's very hands on. Surely this cannot be a long term plan (although it'd be lovely if it was), but it must be putting a lot of pressure on Tuchel to take the pieces and put them together into something capable of challenging.
Side note: not sure if the Granovskaia departure was connected to Abramovich and his shady dealings, but if it was a difference in opinion with the new regime, we should be straight on the phone. Her record in the market is outstanding.
