Former Barcelona boss Guardiola is on a one-year sabbatical from football and is said to be Chelsea owner Abramovich's number one managerial target.
Guardiola's agent claims his client, who has also been linked with Manchester United and Manchester City, will make no decision about his future until next year.
And if he elects to join Chelsea, Benitez - appointed manager on an interim basis until the end of the summer - expects to be among the first to know.
"I think so!" he joked. "I have good relations with Pep so any time I call him, I say, 'How are you doing?'
"I know he is enjoying life in New York, now, with his family."
Benitez doubts his bosses at Chelsea would also tell him if they were in talks with Guardiola, adding: "I don't think that they will let me know. But I don't have any problem. I know the situation.
"I have come to create a competitive team and to win trophies.
"It might be that you can win three trophies, which would be difficult for anyone.
"The worst case scenario - if you win three trophies and then they would say, 'No, we give the job to another one' - I will be so pleased with three trophies."
