Nigeria international Fisayo Dele-Bashiru arrived Rome on Friday night ahead of his Lazio medical.
Dele-Bashiru was pictured at the airport on arrival and will undergo tests on Saturday (today).
The 23-year-old is expected to sign his contract once the medical is completed.
The midfielder moved to Turkish Super Lig outfit Hatayspor as a free agent last summer after severing ties with Sheffield Wednesday.
The Manchester City academy graduate scored nine goals and provided six assists in 39 appearances across all competitions for Hatayspor last season.
Dele-Bashiru will join Lazio on loan for €2m
with obligation to buy at the end of the season for a further €4m.
That allows the Biancocelesti to pay less than the €7m release clause in his Hatayspor contract.
