The winner of national Cup should get a spot in the continental league. 

Winner of the continental should get a spot in the champions league. 

Wont work.  If you see that the new coefficient from each country only gets so many teams that get to enter the CC and CL going forward.  The teams that only get 1 spot will no have the top teams from their country getting a spot in the CC or CL due to this.  

Maybe a cup tournament would work better. 

yes like and in real life

I like It too, more realism, for the game, it's a good idea
