The Argentine international spent last season out on loan at Getafe.
Sunderland's Santiago Vergini
The utility defender spent time on loan at Getafe last season but a deal to join the Spanish side permanently fell apart when the Madrid-based side were relegated to Segunda Liga.
Now the Sunderland Echo is suggesting that Vergini is a target for the Argentine side. However, any deal looks to be difficult, as Sunderland want a fee for the player. The Black Cats are believed to want up to £1.5 million for his services with Boca instead hoping to bring him in on a free.
The 27-year-old joined Sunderland, initially on loan, from Estudiantes in 2014 and signed permanently in 2015.
Despite some good performances for the club he is likely to be best remembered for a glorious own goal he scored against Southampton in October 2014 – which will go down in Premier League folklore for all the wrong reasons.

He played 27 times for Getafe last season and has three caps for the Argentina national team and his departure would certainly help Sam Allardyce start making moves to improve the Sunderland team ahead of next season.
