The 26-year-old Argentinian returned to the Stadium of Light on a season-long loan deal from Costa Rican side Sport Uruguay de Coronado in August last year and has made 35 appearances to date this season, the last of them a start in Sunday's 1-0 derby victory over Newcastle which provided a huge boost to the club's top-flight survival hopes
A successful completion of new head coach Dick Advocaat's mission to keep the Black Cats in the Premier League could have significant consequences for Vergini, and he is open to what might come his way.
He told the Sunderland Echo: "In the contract, it is written that if we stay in the Premier League, I can stay here for another two years
I feel very comfortable here, both at the club and outside the club, so I would be very keen to stay.
"The only downside is the climate and the weather, but even that has been good for the last few days!
"It has been very good to play regularly [this season] and I am very happy
I think with time, I have been able to adapt more to the style of play and also to my team-mates.
"Apart from the struggles we are going through in the league, I have felt very comfortable."
Victory over the Magpies - their first in nine games in all competitions - eased Sunderland into 15th place and three points clear of the relegation zone.
However, that could count for little if Advocaat's men fail to build upon it when Crystal Palace head north on Saturday.
Vergini said: "Every win brings with it a lot of confidence and with a derby game, that is even more the case
In our next game, we need to show the same character and the same spirit as we did on Sunday."
