Rom is magnificent. I wouldn't be at all surprised if he goes back to Chelsea (unfinished business) and tears the league apart. Werner should have had a hatful last year and he's not a quarter of the player Lukaku is. With Havertz, Mount, Pulisic and Ziyech supporting him Lukaku would score 30+, easy (but, honestly, put him in any of City, Chelsea or Utd's line ups and you can say the same).
I'm actually surprised City aren't making a hard run for him, given how badly they need a forward with Aguero gone and really just Jesus to rely on.
