The issue that I have with linking a wasted career with trophies is that it's only in the last decade that some teams could guarantee anything and even then it's only three or four of them which means that vast majority of top players "wasted" their primes.
As an example if you go back to the 90s and 2000s which are the last eras during which top players were spread around Europe and not really concentrated in a handful of teams, the likes of Totti, De Rossi, Montella, Aldair or Totti didn't win as much as their could suggest. And in my opinion they didn't waste their primes, in fact I miss that era I hate this trophy hungry and super team focused era, I hate seeing player move to the same clubs just to be on the bench or be forced into a team that doesn't see their talent valued and showcased. The same applies to a team like Fiorentina in the 90s that has just been slandered in this thread, we are talking about a team that had Mijatovic, Balbo, Toldo, Rui Costa or Batistuta.
To me that's the death of Football as I knew it as a kid. Concentration of talents and focus on everything but actual football games.
