I don't think the license is the biggest concern. The government will be seen as vindictive if they are wilful in blocking the sale of the club to new ownership.
The bigger worry is if Roman digs his heels in because he's losing a 2 billion asset and this period of uncertainty goes on longer. In that case, we'd lose much of what we consider Chelsea today. We'd lose our core players and we probably go out of the top level for years.
