The Azzurri failed with an offer in January for the Argentina International and are now ready to try again.
De Spiegel says that the range of £ 60 million from Napoli was rejected by United and now wants to do business for around £ 45 million.
For his part, Garnacho has accepted that he has no future at United under manager Ruben Amorim and is ready to continue this summer.
The 20-year-old is indeed one of the five united players who told Amorim to stay away from training for the season while their agents tried to deal with new clubs.
