Michael Bradley's agent has welcomed Valencia's interest in the Roma midfielder but insisted his client is only focused on becoming "one of the pillars" of the Serie A side.
But Paolo Alberto Faccini said this was not the case, telling Calcio Mercato: "When there is an interest in a client it is always nice, but right now it does not seem appropriate to speak about other clubs.
"Bradley, I hope, is close to becoming one of the pillars of this Roma team. I think it was one of Michael's best performances if we evaluate it in context. He was coming back from a long injury at a time of difficulty for the team, and he scored his first goal for the club."
Reports have also hinted at discontent in the Roma camp due to Zdenek Zeman's tactics but Faccini played this down, claiming USA international Bradley had belief in his manager's methods.
"I was at home with him after the game and he was overjoyed," Faccini added. "He can give much more, though, and I am convinced he will become a regular in the team.
"Yesterday I heard Zeman say he was glad of the commitment and determination with which Bradley trains. Michael has a great relationship with the boss and believes in his methods."
Meanwhile, new president James Pallotta has claimed that listing the club on the stock exchange is not in his plans - but that a new 60,000-seat stadium complex, which "must be ready for Euro 2016", is.
The 53-year-old took charge of the Serie A club this summer and, despite making the majority of his estimated $200 million fortune in trading stocks and shares, told Il Sole 24 Ore that being a public company was far from ideal for any sports club.
"If you want to win, you have to build and focus on long-term results and that's why I say that sports teams should never be listed," he said.
"A price on the Stock Exchange does not express the value of a team and it is not a coincidence that nine years ago, after the purchase of the Boston Celtics basketball team, we decided to de-list from Wall Street."
Pallotta also confirmed Roma are close to agreeing a deal to vacate the Stadio Olimpico, which they share with city rivals Lazio, and move into a complex which will include restaurants and shops within three years. "I would have used the Coliseum for the new stadium in Rome but they told me it was busy," he said.
"Seriously, we're almost ready; we have already had several meetings with the Mayor of Rome and with the technical departments of the city. We examined 100 sites, selected 12 and finally – with our advisors – we arrived at a shortlist of three.
"Now we are at the final choice: a stadium which will have 60,000 seats plus shops and restaurants. It was designed by world-renowned architect Dan Meis."
