The 25-year-old defender found it difficult to leave the Granata for the Old Lady during the summer but says he felt right at home as soon as he arrived at Juventus Stadium
The Italy international came through the youth ranks at the Granata but made a €13 million transfer to their cross-town rivals during the summer.
Ogbonna freely admits that it was a difficult decision to cross the Turin divide but says he now feels right at home at Juventus Stadium.
"I felt like a Juventino from the first day, even though it was not easy to forget 12 years with the Granata," the versatile centre-half told La Stampa.
"Juve are different. They are more distinguished and the objectives are different. There is only one target: victory."
Ogbonna has yet to nail down a regular berth in Antonio Conte's starting line-up but says that he is learning all the time.
"Conte wants me more aggressive, but in the competitive sense and in the reading of the game," he explained.
The 25-year-old Ogbonna has made five Serie A appearances for Juventus so far this season.
