Rodri and John Stones are the foundation of the Treble win.
Many other players contributed a lot to the Treble: Ederson, Ake, Gundogan, KDB, Bernardo, Haaland. You are entitled to think what you want, but, IMO, Stones didn't contribute more than those players. Gundogan was carrying us in the final weeks, Haaland scored 52 goals, KDB was KDB. Grealish and Bernardo were top quality, too. Also, Rodri was different class.
To say that only Rodri and Stones were the foundation is a bit silly.
If KDB and Haaland were in the same form as last season, we'd have probably won vs Real and competed for another Treble. Stones was great last season, and so were many other players.
