The next target for the Bolton-born centre-back is to secure a place in the squad for the upcoming tour of the United States.
Asked about the prospect, he added: "I’d say so, yes, but I’ve got to take each step at a time.
"It’s not that far around the corner and there will be players returning from the World Cup so if I can hold my place [in the squad] that will be one thing accomplished."
Chirivella, meanwhile, is aiming to make an impact at Anfield after enjoying a successful loan stint at Dutch outfit Willem II last season.
He said: "It was a good period. I played a lot of minutes that I needed. I think I’ve come back in better shape physically and hopefully I can get more minutes."
