Former Tottenham midfielder Sandro is joining Serie A minnows Sandro.
Sky Sport Italia says the 28-year-old has already undergone a medical with the side currently bottom of the Serie A table.
He is due to arrive on a six-month loan from Turkish club Antalyaspor.
Sandro spent much of his career in the Premier League at Spurs, QPR and West Bromwich Albion from 2010 to 2017.
This is the second reinforcement for Benevento in the January transfer window after Maribor centre-back Jean-Claude Billong arrived for a reported €2m.
