They know the price. They've been talking with us for about a year(??). The price is well published too, several ways to value a football club, but a widely trusted rule is 5-6 times revenue, which is broadly accepted.They have to say they made an enquiry.
Have you ever asked the price of something, got told the price, put it back and thought "Not today"?
Same process. They have to publicly come forward with any interest.
