The defender thinks that he might not be ready to make an impact right away following his transfer, but is keen to learn from his team-mates
The Italy international, 25, joined the Serie A champions for a transfer fee potentially rising up to €15 million (£13m) earlier this summer and revealed his desire to learn from his new team-mates as he aims to become a key player.
"It's a little bit difficult for me to enter into the team dynamic because the spirit of the team in defence is different from everything I've worked for all these years," Ogbonna said.
"I'm having to adapt to a new style of play. I'm just looking forward to learning a lot from the more expert players.
"I think I'm in good physical condition but obviously I need to return to top shape before the beginning of the season. I train hard every day and I hope to continue improving like this.
"Our gameplan is mostly based on setting up play for the forwards. I've been asked to fill that role for the team to stimulate more forward momentum, so to play more aggressively."
Ogbonna could make his official Juventus debut in the Supercoppa Italiana clash again Lazio on August 18.
