The Italian centre back, 27, left Juventus for Upton Park over the summer, and was one of Slaven Bilic's biggest signing having impressed in Serie A.
Strong and athletic, Ogbonna has earned ten caps for the Italian national team, so it was something of a coup when West Ham managed to lure him to East London over the summer.
So far, Ogbonna has had a couple of injury problems, but now he is fully fit, he is starting to impress in the West Ham defence, playing a key role in a recent upturn in the club's defensive displays.
With just three goals conceded in the last seven games, Ogbonna has been vital for West Ham during a tough time, which has seen them hit with a string of injuries to key players.
Now, Ogbonna has noted that a chance in system and tactics helped West Ham get through their tough period, adding that Bilic's men remind him of Juventus for their mentality and resiliency.
Speaking to The Sun, Ogbonna also noted that he thinks West Ham could finish in the top four, given that they currently sit just four points away from the Champions League places, and are now seven games unbeaten.
"We have had a bad period because Manuel Lanzini, Dimitri Payet, Enner Valencia, Victor Moses and Diafra Sakho have been injured. But we changed our system really quickly. Also our tactics," said Ogbonna. "It’s not been easy but in that period we have only lost once in eight. Do I recognise this mentality and resilience from Juventus? Yes I do. We have a lot of character to change, to suffer, to maintain our temperament."
"When I came from Juventus I felt there was an opportunity for me and the club. I knew the coach and the quality of the players. Can we finish in the top four? Why not? We have to take care of ourselves and focus on what we want to do. We will see at the end of the season," he added.
