You guys can blame Sarri for most things (which is justified) but your board is not without a big part of the blame
Your squad composition and planning have been a disaster for close to 3 years if not 4 years now
You sell some key players in vital positions (Vidal, Pogba) and doesn’t replace them with anything near their caliber
You by Ronaldo but doesn’t buy any midfielders to feed him and lacks a clear gameplan how to get the best out of your offensive players. You simply can’t win the biggest titles if your midfield is not up for the task. There’s a reason the teams that won the CL in recent times had some of the best passers and most dynamic midfielders
Liverpool might been an exception when it comes to the best midfielders, but their style makes them hard to counter as they play with so much power
Juve lacks a Kroos, Modric, Thiago, Kimmich, KDB type of player. Someone to dictate the game and can make the ball switch fast. Pjanic could maybe do it but he didn’t impress much in that sense imo
Maybe you’ll get that from Arthur
Burn in short you really need to look at your squad planning, it looks so random who you buys for that midfield
Juve in 2014-15 had an average attack (sorry to Tevez and Morata) but a wc midfield
Juve in recent years had some really good attackers but a below average midfield compared to the other European clubs
