As long as we don't get rid of this issue, we won't win CL anytime soon.
Just look at favorites - they have stable squads and retain their best players while adding to it, even little by little.
Juve needs to sell key/potential top players pretty much every Summer to cover the holes in the books.
They are also not playing in backwards Serie A.
The English clubs have tv rights.
The Spanish giants have the banks and their FIGC bailing them out. Also have a bigger fan base, bigger stadiums and reside in bigger cities.
Bayern plays in a richer country and usually gets all their local talent dirt cheap.
And some have sugar daddy's.
Now if Exor doesn't want to burn out money on Juve anytime soon, the trend is going to continue for many years to come, because with Ronaldo I think we have achieved peak financial power.
It's all downhill from here, as the the sporting powers in Italy seem to be stuck in time.
