I don't think they will want to do that, so Coutinho would have to do what he can to force such a move.
FSG do not appear to be simply about selling assets and making money, because they know they require a quality team on the pitch, which means they must invest in new players and approve wage increases for our best players - especially with a manager like Klopp to keep happy
I think the issue with them is not about squad asset-stripping, but rather the level of investment they are prepared to sign off. That's what will keep players who will be coveted by the richer, more successful clubs at Anfield and out of the clutches of Chelsea, City or whoever - winning trophies and being a regular challenger for the title
We have two players right now who most of the top teams here and abroad would be interested in: Mane and Coutinho. We need to get more players in at that level to ensure we keep them and build the team into what we all want.
That's where FSG have failed to do enough, and this summer will be an indicator of that ambition and if it has changed
If not, Coutinho will leave. And he will be correct to do so.
