I am of a general opinion that we should be looking to sell the players whose contracts expire next summer, should they not extend. Morelos, Kent and Aribo are far too valuable as assets for that asset to be worth £0 to us next summer.
However, £6M is unacceptable and I'd rather keep Morelos for a season and hope we can remind him of how much he loves the club and maybe even get him to sign an extension. I know that's unlikely, but I think Godson's mind changed last season.
We all know that we support a special club, and it can take just one moment for a player to remember and embrace that, and come to a conclusion that they want to stay even longer. Staying with us gives him the opportunity to become a club legend. To some that is a greater achievement in a football career than the leagues you played in, or the players you played against. And for some, even the trophies that you win. An example being Alan Shearer may be prouder of his legacy as a Newcastle Utd legend than his PL medal with Blackburn.
I'd also fear that selling at well below market value sets a bad precedent for future approaches for our players. This can lead to not getting true value, and may also lead to disgruntled players should they disagree with our valuations of them, citing any cheap sales as evidence of this.
