I'd have to listen to the interview again carefully but I think in the same way you used "Superstar" in quotes I think Steve Parish did the same, but then he did throw in 'generational talent' which is a bit more open to interpretation but builds the tone nicely.
As it was a slightly mixed message. On the one it was 'hands off our prize asset' but on the other it was of course 'he is for sale (at the right price)' and of course, as it's Steve, done very publicly - but in a very reasonable way. You might say it was it a final sales pitch to Liverpool or anyone else who might be interested and could offer more but holding back for a late last deadline day bid
Which so far hasn't had any impact. But at the same time it helps the bigger picture.
We've just lost Olise for relative peanuts for his talent because of the release clause value. So it makes it clear as other posters have put it 'we won't have our pants pulled down' or 'walked over' on the valuation. With Eze, Mateta , Wharton getting a lot of interest, as well as the ridiculous low offer on Andersen. it gives the right message to the big time (and small time) 'vultures'.
I think Eddie Howe said in an interview recently how they have had to fight against the 'Newcastle Tax' of clubs doubling the price when it was them on the phone which they by holding firm on prices.
Palace doing similar work here. No FFP / PSR problems. No cash problems. Top dollar only.
But finally the rumour from yesterday was that Palace's actual valuation WAS met in the final offer. It went to Glasner who said he wanted Guehi to stay and it went to Marc and he wasn't that bothered about Newcastle so he is not making a fuss about wanting away.
So we are happy to keep him. If he has a great season then his value won't dip too much as he reaches 1 year on the contract and interest intensifies. But it might. Or he gets injured. High Stakes.
