I really doubt that. I don't see a single coach capable of achieving more than Flick with this squad's quality and depth. Especially in the CL against billionaire's toys and statesponsored washingmachines. Players like Martin, Cancelo, Balde, Araujo, Casado, Rashford, 39y old Lewa, Ferran are good enough for a weak LaLiga, but not European top-lvl. And I'd also argue players like Fermin, Eric, Olmo, Kounde can have top games, but also bad games where they're useless or worse, a liability. Simply put they're not constant enough or somewhat limited. Then you have Bernal and Gavi you can't really predict the form they can reach again after ACL. We have only Pedri, Lamine, Frenkie, Joan, Cubarsi and Rapha good enough if they're fit for the highest level. That's 6 players.
