I don't think we can afford to give up because I just don't see how we're getting anything approaching a decent return on our investment. We bought him for a good fee, but more pertinently, he's rumoured to be on an absolute shed load of money currently.
Only a handful of clubs can take our higher earners, that is the simple reality of the situation. Only a reduction in salary could induce another category of buyer but what possible incentive is there for Martial to do that? I'm always confused when I see people saying we should sell him for a good fee, but what are they honestly expecting out of that situation given the overall financial package Martial represents alongside his awful form and inconsistent play? Which clubs want him?
I think we'll end up keeping him quite honestly. Maybe he'll be a decent rotation option on the left, the odd game down the middle. It won't justify his place within the squad as a high earner, but it's probably the compromise we'll have to accept. Or he might have enough of his good spells among the lethargic showings to call it a good season.
