Agreed.
Letting Llorente go without replacing him ranks alongside not replacing Dembele as one of the mysteries of the universe. A 17 year old is not a PL understudy.
Who knows what will happen if Kane picks up another injury. Our tactical change to play out long from the back requires us to have a target and Son, Dele, Lucas are not it.
Don't worry. Fellaini will replace both of them
