My prediction is that Eze gets a bunch of games this Season playing as the false 9. I don't think Martinelli will play there and I think Eze is better suited to the role than Trossard.
I also don't think he will play as a sole 10 very often.
I think he’ll likely start as a left sided midfielder. But he can also play that false 9 and no10 role.
gives us great forward options
