The controversial figure has responded to an Italian politician's criticism of Juventus' management by launching a scathing attack on Massimo Moratti's club
Moggi, who was handed a ban from Italian football for life in the summer directed the insult towards Inter supporter and politician, Ignazio La Russa, who had previously criticised Juve's management.
In an editorial for Italian newspaper, Libero, Moggi wrote: "When Inter did not win it [Serie A title], it was because they bought Hakan Sukur and Taribo West, and because they let their best players, [Clarence] Seedorf and [Andrea] Pirlo go to Milan in exchange for [Francesco] Coco.
"Juventus on the other hand bought [Gianluigi] Buffon and [Zinedine] Zidane. They [Inter] started winning when they took advantage of Calciopoli, taking Juve players [referring to Patrick Vieira and Zlatan Ibrahimovic] and brought in Jose Mourinho.
"But now Mourinho is gone and the errors have surfaced again. There would need to be another Calciopoli for Inter to start winning again."
Inter suffered a shock 1-0 home defeat to Trabzonspor in the Champions League on Wednesday night.
