Zamparini has previously stated that he wants around €50million for the highly-rated 22-year-old playmaker.
“I cannot say who has the advantage between Chelsea, Manchester City or Roma. I can only underline that I’m interested in cash deals,” Zamparini told the Gazzetta dello Sport.
“We are at the final stages and will evaluate the offers on Tuesday. When we see which the real proposals are, then we can go forward.”
