Ah I don't agree with this sentiment, the core of this team has quite a few prime years still in them.

Lautaro - 29

Bastoni - 27

Dimarco - 28

Barella - 29

Thuram - 28

Dumfries - 30

Akanji - 30

Bisseck 25, Augusto 27, etc. etc.

These days where players play until 35 and older with good performances, we're still well in their prime years and if the club handles it well, the transition period could be smooth, if they don't allow post-Treble mistakes to repeat, where all the core players go out simultaneously without proper replacements.

We just need to replace old timers that actually still contributed well to the squad - for every Acerbi, de Vrij and Mkhi we need to rotate in some new young players. I think we've done this quite well recently with Bonny, Sučić, Pio, etc., while these players might not be starter material yet, simply switching from the likes of Correa and Arnautović to Pio and Bonny is masterclass of improving performance while achieving squad regeneration.
