The main problem with this kind of teams is that one, they re build the teams every single season after doing great or not, and that for sure kills the real develop of a team, you need several seasons to become a real contender team, just look at Atalanta they have a ton of season before they were a great team.
Truly a rebuild after every season ends does more harm than good to a team, players having to start all over again to cope and the incorporation of new mentality and other too many things that has to be done just to get back inform again and do good or better, the most applicable that can be considered healthy for the team will be if they readjust tactics, formation and strategy so as to enable them do better than they have in the previous season, that will be a very possible and achievable.
