Giovanni Galeone feels Max Allegri needs a "miracle" to win the Scudetto with Juventus.
Galeone acts as a mentor to the Juve coach.
"This Juventus side need at least for new signings, if not, they'd need a miracle to be competitive at a high level, especially after Pogba's injury," Galeone, a former coach and close friend of Allegri, told La Gazzetta dello Sport.
“Have you seen Juventus' midfield against Koke, Saul and the others?
“De Ligt was exceptional on the right but suffered a little on the left. They signed Bremer, who has never played as a left centre-back. Did you watch the game against Atletico? Morata joked with him. He had never made such a bad impression at Torino.
“It wasn't possible [to sign Koulibaly and keep De Ligt] and I understand that, but the first Juventus of Allegri had an iron defence which is no longer there. Perhaps, Max is considering switching to a three-man defence."
Asked where Juve need to strengthen, Galeone continued: “Surely a quality midfielder who can give order in the middle of the park. Leandro Paredes would be good because Locatelli is not a Regista. They also need a striker.
“Morata is tactically reliable, he can play as a centre forward, support striker or winger. With one signing, they'd solve three problems.
“Are we talking about the Juventus that wants to win the title? Because a team that wants to win and be competitive in Europe should not have problems in meeting the coach's desires.
