Inter Milan full-back Davide Santon is undergoing a medical at Newcastle.
Santon, 20, is under contract with the Serie A giants until June 2014 and, despite reported interest from Roma, Newcastle look set to win the race to secure his signature.
It is suggested a fee in the region of £5 million has been agreed between the Magpies and Inter as the Premier League club look for a replacement for Jose Enrique, who joined Liverpool this summer.
''At this time there is no possibility that Santon can join Roma because right now the aim is Newcastle,'' said Santon's agent Claudio Vigorelli to Corriere dello Sport.
The Italy international has been with Inter since 2008 and made 16 appearances in all competitions during the first half of last season before going on loan in the second half of the campaign and making 11 league appearances for Cesena.
