Percassi told Tuttomercatoweb that the club were relaxed about the situation and would evaluate any approach in their own time.
"We have no official offers, only interest from other teams. I think it's unlikely that teams will make a move before the end of the season. Interest in our players is normal, but we'll evaluate them at the right time with great serenity and calm."
Manchester United are understood to be planning a significant midfield rebuild ahead of next season's Champions League return, with Casemiro confirmed to be leaving and Manuel Ugarte expected to be made available. Kobbie Mainoo recently signed a five-year contract extension, meaning any new arrival must complement the academy graduate in a two-man central pairing.
Éderson, 26, made 40 appearances across all competitions this season, scoring three goals and providing two assists. He picked up the man of the match award on Sunday after scoring the opener in Atalanta's 3-2 victory over AC Milan at San Siro. His contract expires in June 2027, which means this summer represents the optimal window for Atalanta to secure a meaningful fee.
Atletico Madrid had reportedly agreed personal terms with Éderson in January but were unable to find an agreement on wages, opening the door for other clubs. Italian journalist Nicolò Schira reported earlier this week that United had already agreed personal terms with the player on a contract until June 2031 at €5million per year.
Atalanta's asking price is around €45million. United have indicated willingness to pay in that region. The two clubs have not yet opened formal negotiations, but all parties appear to be moving toward an agreement. Percassi's measured public tone is that of a man who knows a deal is coming — and is in no rush to make it cheap.
