As far as I know, Genoa isn't in major financial troubles and don't need to sell him. Why wouldn't they drag their feet and wait to see if other larger bids come through?
The owe tax man 106m from the previous ownership. I posted about it earlier

“But by the end of January 2024, 777 Partners will have had an answer to another key question with regards to one of its football assets: Genoa.
Having purchased Genoa back in September 2021 for a sum of around €150m, according to Reuters, Italy’s oldest club were relegated at the end of the 2021/22 season before bouncing back with promotion in the 2022/23 campaign.
When 777 Partners acquired 99.9% of Genoa's capital, a statement that accompanied the purchase of the club, without highlighting specific financial details, stated that the new owners would “assume certain related liabilities.”
A chunk of those liabilities come in the form of a tax bill due to the Italian tax authorities. According to investigative journalism
website Josimar, €106m was due to the taxman.
At the end of October a deal was struck between Genoa and the Italian tax authorities that would reduce the indebtedness of the club to the taxman, reportedly reducing the tax burden by some 65%. The deal would see repayments spread over the next decade.
But that agreement has to be ratified by the Court of Genoa, with a decision to arrive before the end of January. If the Court reject the agreement that was reached it would create significant problems for the prospective Everton owners and the club, which would, according to Josimar, face the threat of bankruptcy.
Sources close to 777 Partners claim that the Genoa owners don’t anticipate any issues with the decision, with the renegotiation done do achieve more favourable terms for the ownership having acquired the tax liabilities from the previous owners of the club.”
