Sampdoria director of sport Carlo Osti has extended his deal to 2018.
Osti's deal was due to expire in June.
"I thank the President, lawyer Antonio Romei and all Sampdoria's collaborators," said Osti.
"I am tied to them by a rapport that is not exclusively professional and from June to today we have worked to give strength to the club, our Coach Sinisa Mihajlovic, the team and our youth academy.
"The prerogative of this Sampdoria is shared objectives and this is why I am happy to be confirmed in my position by the President."
