Sunderland boss Gus Poyet has made his second signing of the transfer window by acquiring Argentina defender Santiago Vergini on loan until the end of the season.
After signing full-back Marcos Alonso from Fiorentina on the same terms earlier this month, Poyet has added centre-back Vergini from Uruguayan side Atletico Fenix.
The 25-year old has previously played with Olimpia in Paraguay and Verona in Italy, while most recently he was on loan with Argentine side Estudiantes after a spell with Newell's Old Boys.
Vergini's one and only cap for his country came in 2012.
