If he had come he wouldn't have been an automatic choice for up top, Aguero would. Maybe that's why his or our or both our interest cooled. Possibly we indicated he would have been played as a wider forward than he fancied.
To be honest I think we will be much better off with a goal scoring wide player than is capable of a more central role when required. That said Pep is a fan of a false 9 whether it's a winger or midfielder in the role so not having Aguero or Iheanacho available for any games wouldn't faze him if he has the right midfielders / wide players to work with.
