Let’s face it for 4-5m you can get a fantastic midfielder to replace Hamer. Especially if we get 12m in which I would take.
The problem is he won’t be Hamer who was the best statistically in the division last season and universally adored by cov fans.
Personally, if offered less than 10m I would swallow the cost and keep him as he is that good and key to the team.
If over 10m then I would sell as it’s too good for a player with 10 months left.
and if we have a bad season or two. Demand will massively drop off. It’s swings and round abouts.
FWIW this system isn’t perfect as no system will be. This is the fairest I can see even with its imperfections which I acknowledge
