It'll be aimed at Coutinho himself more than the club, if it's true. So basically trying to get him to kick up an almighty fuss/say he'll down tools/etc/etc. Not that it'll necessarily cause him to do that or work if it does.
You think? Such a short deadline over a game weekend doesn't give him much of an opportunity to kick up a fuss. I suspect it was more a case of hoping we were bluffing and to get us to at least negotiate with them, if not accept the offer.
