From what I understand the King power family business loaned (‘invested’) c£100million in their first 6 years of ownership and similarly now another c £200 million during the last 4 years.
Quite a commitment!
Hopefully the club is still worth £250-400 million should they want to sell.
Where we go from here and the value of the club is dependent on staying in the PL so one would imagine the family will not shy away from taking big decisions should they feel they are needed.
