Sunderland's Santiago Vergini

The defender has played for the Argentina national team, but struggled for consistent form while at the Black Cats.

Sunderland defender Santiago Vergini has completed a permanent switch to Argentine giants Boca Juniors, as confirmed by the club's website on Monday.

It's fair to say that the Black Cats didn't get the best out of the defender, even if he did play his part in Sunderland's amazing escape at the end of the 2013-14 campaign, under Gus Poyet.

Vergini was brought to the Stadium of Light in the winter transfer window of that season, initially on loan, with the move being made permanent in a complicated agreement based on the club's survival from relegation after 18 months in the North East.

Poyet's second campaign in charge was a difficult affair even though Vergini featured regularly at both central defence and at right back. The Uruguayan left with the Black Cats in 17th position in March, just out of the relegation zone, but when Dick Advocaat took over the 27-year-old Vergini found himself relegated to the bench soon after and he made just a handful of appearances in the remaining fixtures.

Last summer it was made clear that Vergini was unwanted in the North East, despite the club being obligated to sign him, and he spent a campaign on loan at Getafe with a view to a permanent transfer. Unfortunately for player and both clubs, that was voided as Getafe were relegated following a disastrous second half of the season.

Boca have signed Vergini despite concerns over his fitness, offering him a one-year deal rather than a three-year contract according to the Chronicle.
