The report states that the Italian Under-20 international was looking for a move away from Brammall Lane under former manager Nigel Clough, but has since been guaranteed playing time by new boss Nigel Adkins.
He is ready to sign a new contract, and is willing to shun interest from a host of bigger clubs than the Blades to agree a three-year deal.
Attacking midfielder de Girolamo, 19, progressed through the Blades’ academy system to become a member of their first-team, and although born in Chesterfield is an Italian youth international.
He has been capped at every youth level by Italy from Under-18 to Under-20, and his impressive potential saw him linked with a move to a host of big clubs.
The Mail report claims that the youngster turned down interest in him from Celtic, Sheffield Wednesday, Benfica, Southampton, Juventus and Napoli to sign the new contract.
It is a decision which many may believe is strange, but staying with United guarantees de Girolamo consistent playing time and a way to develop, and it will surely not be too long before he earns a move to a bigger club following impressive performances on the field of play.
