Martial was here this year as the clear first choice since pre season though, it’s not as if we kept him on that wage intending on using him as a spare 3rd option. The season before as soon as it was evident that he wasn’t getting games ahead of Cavani, Ronaldo and Greenwood (which is a clusterfeck of a situation), he left on loan to Sevilla, and Greenwood was never officially part of the CF rotation, he was more of a wide forward in selection, so effectively Martial left when there were two players ahead of him in the pecking order.
And we don’t know what sort of budget we are playing around with in the summer. We need (urgently) a striker, a playmaking CM, another CB (assuming one of Maguire/Lindelof leaves) and (possibly) a new keeper, RB. That’s a lot of positions needing investment in that getting in a young prospect good enough to be a PL back up might just be out of our reach, without selling/vacating the wage bill.
Realistically, I think he will be here next season as 2nd choice because his wage/injury record will prove a stumbling block to most teams. But in the event we do get in 2 strikers, then that’s probably it for Martial, whether it’s via a straight sale or another loan. And while a few are clearly irrational with their desire to sell him or their armchair psychoanalysis of his mood/behavior, the point that it’s risky having a player with his injury record as part of rotation in a position so vital is fundamentally sound.
