The agent of Lazio defender Francesco Acerbi is aware of Chelsea's interest.
The veteran stopper has been linked with Chelsea and Inter Milan this week.
Federico Pastorello told FCInterNews: "I read about Chelsea and Inter, but I don't know much about it.
"What I can say for sure is that Francesco is a defender who can play for all clubs in Europe."
The 32-year-old still has some years left on his current deal, which is set to expire in June 2023.
