Capuano was scouted by Bolton on the weekend.
"I know someone had come from England more than once to see him at work and I understand that they were emissaries of Bolton," Delli Carri told skysports.com.
"But no-one has stepped forward with us, formulating a proposal. I don't know if the English club is really interested in Capuano, but I can confirm that many clubs, including Italian, are watching to him.
"We speak of a young player who is showing important qualities and is part of the Under-21 Italian national team.
"Can he leave Pescara in January? We want to keep Marco at least until June, and we believe it is also his interest to grow more here with us. In any case we have not received any official offer."
