I think the balance of that is horrible to be honest. None are creators, none are players who hold width well, rashford and Greenwood do their best work by runs in behind to get shots off and score goals. Hojlund is a traditional 9 not a false 9 so you don't want to crowd him out. You need width and creators on either flank like Bayern had with Lewandowski central. Can have a wide forward on one side but you want a proper winger on the other side. Garnacho might work long term if you want balance Greenwood, but if it's Rashford on the left then the closest we have to a functioning partner on the opposite side would be Antony. But he's meh. Amad is more a guy who drifts inside and is a playmaker, closer to mata.. So ideally I think we still need someone like Neto maybe. But the Greenwood hypothetical doesn't mesh with our team beyond being a backup to hojlund. I don't even think his potential as a wide player was ever that high anyway, where he once had elite potential was IMO up top, but who knows where that is now.
