Concerns arose last season after the Hammers faithful had to change locations from the Boleyn Ground to the new London Stadium, however, Ogbonna claims the fans are like family to him and his teammates.
"The fans are really important for us," Ogbonna told the club's website.
"I cannot compare our fans with other fans because we are West Ham, we are more than a club and we are a family.
"For us, it's important that we have people behind us. It makes things much better for us."
