Pastore is part of a bidding war in Europe after President Maurizio Zamparini confirmed a 50m price-tag.
"Pastore? Everything is possible," agent Marcelo Simonian told romagiallorossa.it.
"Their new director of sport, Walter Sabatini, has an excellent rapport with all of us. If this transfer means having the money, then it's certainly possible.
"The President has set the selling price, so things are clearer now. I would see him do very well at Roma. This is an extraordinary club with an amazing city and fans, so the whole idea of joining the Giallorossi is very attractive."
However, Simonian was quick to point out that formal negotiations with Roma have not even started.
"I've known Sabatini and Franco Baldini for many years. They represent a guarantee and I'm sure everything will go well in this great project."
