There's an app that does that.
I bought it and spent a about a week playing it. Good fun.
Football Chairman Pro: Paid, offline, real club names, real player names but afaik player stats are randomized. Only the leagues of the country you select are simulated (+plus Champions and Europa League teams from other countries). Other country leagues are available to download on dev's website for free.
Bigger numbers don't win everytime. There are mechanics like player/manager/fans happiness, player form and fitness. Training, youth management, stadium building etc too. Suitable for playing on commute. Smooth and well optimized.

give a look at this...
for the complexity problem... i think it would be good to have only a "coaching skill level" and the "fans support for the coach %".
I am reclutant too about the tactics and something like that..
it would be only a good way to recycle old players and close the circle.
Have you tried out Football Chairman?
What am I going to get from this game that I don't get in the more polished one you borrowed heavily from?
