Former Juventus chief Luciano Moggi has launched a furious attack on the current board over their transfer policy.

Regarded among the best sports directors in the game, Moggi left the Bianconeri in 2006 as details of his involvement in the Calciopoli scandal emerged.

Moggi said: "It's a team that has been built very badly, full of suspicious tactics.

"Juventus have some very good players, but they are put on the pitch without respect for their characteristics. Melo is a good anchor man, but he is deployed as a playmaker. Diego is a trequartista, but he is worked as a central midfielder.

"I am convinced that the role in which he would best adapt himself, for his qualities, would be that of a second striker.

"Zaccheroni has done well in not starting him against Siena. It'll give him motivation. Diego has up until now not shown himself to be in a position to bear and react to the criticism.

"The draw with Siena is something of which Juventus should be ashamed. From 3-0 to 3-3 and Siena also hit the woodwork.

"Grygera's performance exceeded expectations. But perhaps the team was tired after the challenge with Fulham, but let's say yes or no that they are a midtable side in Italy…"
