Martial isn't competing with Cavani anymore. He is completing with Greenwood! Cavani has come in and the penny has suddenly dropped with everyone. Collectively we have all acknowledged, "Oh, that's what striker looks like. That's how they run off the ball and create space. That's how they drag the centre backs all over the place. That's how they dive in to head anything coming into the box. That's how they track back to win the ball and bring others into play. That's how they score the winner in a tight games. That's how they rise to the big occasions. That's a proper centre forward."
Martial is way way off the standard required at a top club. He is 25, and still doesn't know his best position. He wants to be a CF, but doesn't possess any of the qualities to perform that role. Greenwood is ahead of him in that role. He has had lots of, "this is his chance to prove himself now" seasons. And has never really nailed his position down. Twice now, we have brought in veteran strikers and they have both pushed Martial out. If he was better than them, we would never have done that. Selling Lukaku was his big chance, and he fluffed his lines again.
If someone puts a bid in this summer for Martial, I would take the money and invest it in quality CDM.
