At the moment I find there are a lot of stories about already established clubs and getting them back to the premiership. There is also no shortage in stories about clubs already achieving Champions League places. Most of these stories are in England too, so if I were you, I would do a lower league foreign club. Possibly in Spain and try to eventually break into the top 2 so you can rival Real Madrid and Barcelona. Personally, I would read that story, but it's your story, ultimately, the decision is yours. Good Luck I will definitely read your story no matter what.
