Stefano Domenicali was baffled on Friday when reporters asked for his thoughts on a war of words with Red Bull counterpart Christian Horner.
"Me? That's the first time that I hear that," said the Ferrari team boss.
Media reports said Horner had responded angrily to some recent comments made in the specialist press by Domenicali, including the suggestion that Red Bull is a one-man team with star designer Adrian Newey at the helm.
And the Italian had told a German newspaper that Sebastian Vettel is not yet a true leader.
Horner hit back by insisting that Red Bull doesn't "disrespect or underestimate the achievements of our peers".
That's a new one. I will speak with him, without speaking to journalists
When told Horner apparently had a problem with some of his comments, Domenicali said: "That's a new one. I will speak with him, without speaking to journalists. I want to see what he's saying.
"I don't think that I've said something strange but it's interesting to see Christian's reaction. Maybe he will have something to say to me. He knows my telephone number," added the Italian.
