Benfica defender Maxi Pereira is said to be a target for Sunderland, according to talkSPORT.
The Black Cats have reportedly been watching Pereira for some time and feel that he could bring a lot of quality to their first-team squad
Although the Uruguay international is 30-years-old now, Sunderland still feel he has enough about him to be a valuable addition and they could make a move to sign the right-back in the summer.
Pereira is said to have been identified as a potential summer signing by Gus Poyet, but the club remain interested even after parting company with the 47-year-old coach.
What would the impact be for Sunderland?
Pereira is an attacking full-back, whose main strengths lie in getting forward, so his addition could be vital for Sunderland.
The Wearsiders have lacked a cutting edge throughout the season and bringing in players that can offer them more in an offensive sense will be important for the next campaign.
Pereira would certainly do this and he would also add cover in a position where Sunderland are in desperate need of recruits.
The Black Cats' squad is short of defenders and Pereira would increase their options in an important area.
