Chelsea look set to be tested by Torino for the signature of loanee Ola Aina.
According to The Standard, the Italians want to sign the Nigerian on a permanent deal during the January transfer window.
The wing-back has been at Stamford Bridge since he was ten-years-old. Since then he has progressed through the youth ranks, going on to make six first-team appearances.
Regular first-team opportunities have been rare, with the 22-year-old spending last season on loan in The Championship with Hull City.
Aina has made a bright start in Turin making eight appearances, impressing Il Toro boss Walter Mazzarri.
