Former Juventus fantasista Diego is unsurprised by the problems being encountered by the Old Lady.
The Turin giants made mass changes in the summer, which included selling Diego to Wolfsburg, after a disastrous 2009-10.
But a season later and the Bianconeri are still struggling, a fact the Brazilian blames on the club and not the players.
"The squad has a lot of good players in it, but they need to be managed better from the outside," Diego told Sky Sport Italia.
"Whoever is making the decisions at the club doesn't know a lot about football," continued the attacking midfielder.
"I saw the game against Palermo and it seemed to me that my ex-teammates were never at their best.
"It is not Juventus-like to fail to qualify for the Champions League. I hope that they can recover but it won't be easy as I saw a side in difficulty."
The Turin giants lost 2-1 at Palermo, their fourth League loss from the last six games.
Juve are currently eighth in the standings, six points behind joint-third placed teams Inter and Lazio.
