I'm not sure tbh. Aguero's just too good to be 2nd choice, even if his form isn't perfect. The level you'd have to be at to fully dislodge him would need to be Messi-esque. Other than that he'd need to be in sharp decline and that's not happening. The best Jesus can hope for is that he hits a level whereby he's being rotated with Aguero for reasons beyond preserving Aguero's fitness; such as tactics and things like having 'more rhythm'. Kind of like what I expect to see from Walker/Cancelo or Bernardo/Sterling/Mahrez. And that's ideal because it keeps things competitive too! It looks like Jesus is approaching that level though.
