AS Roma have insisted Daniele De Rossi is not for sale amid reports Manchester United are still targeting the highly-rated midfielder ahead of Monday's transfer deadline.
Club director Mauro Baldissoni told Sky Sport Italia before Sunday's match at home to Verona he would say "no thank you to any offer" for Rossi.
Roma are keen to make amends for last season when the Giallorossi finished sixth in Serie A and out of Europe before losing the Italian Cup final to fierce city rivals Lazio.
Baldissoni added: "If a formal proposal comes in from Manchester United or any other club, we will always say 'no thank you', as would the player.
"The team and Daniele have just finished a season that did not go to plan and both want to make up for that."
Baldissoni said club icon Francesco Totti, currently in his 21st season with Roma, could be offered a new deal but would not hold the club to ransom.
His contract expires in June 2014, and although Baldissoni said talks on a new deal are ongoing, he added: "If you're asking if we are afraid of losing Totti, the answer is no."
