Rashford, Garnacho, Sancho, Antony, Amad. Garnacho is still developing and the same for Amad it seems. Other 3 won't contribute enough in terms of G/A even though they should with their age and experience. So that's 5 wingers but not one that guarantees you plenty of goals and assists the way all those City, Arsenal, Liverpool etc wingers do.
Then we've got Hojlund and Zirkzee as ST options and though I like them neither is finished article. So that's 7 players for 3 positions (soon probably 6 with Sancho leaving) but you're not confident they'll contribute with enough goals. We'll probably rely too much on Bruno again.
