Fabio Borini is to undergo a medical at AC Milan on Thursday as the Sunderland striker closes in on a return to Serie A.
Press Association Sport reported that 26-year-old Borini, also linked with Lazio, flew to Italy on Wednesday.
Reports in the Italian media suggested he will complete a £5.3 million permanent transfer, although details of the proposed move are still to be finalised.
A successful conclusion to the negotiations would see Borini leave the Stadium of Light two years after his £10m switch from Liverpool on a four-year deal.
The former Chelsea trainee has made a total of 90 appearances -- the first 40 of them on loan -- and scored 17 goals for the Black Cats.
