The Black Cats picked up a 1-1 draw at Southampton on Saturday, though will be disappointed to have conceded so late to Virgil van Dijk's equaliser.
Now a point clear of the drop, Sunderland will be hoping to pick up some more momentum and save themselves from relegation, with manager Sam Allardyce currently grinding out results.
'Big Sam' will want to put his own stamp on the team whether Sunderland stay up or not, and he has made a great start in the transfer market, given that January additions Lamine Kone, Jan Kirchhoff and Wahbi Khazri have all impressed so far.
Now though, The Sun report that Allardyce is ready to raid his former club Blackburn, as their star defender Shane Duffy has become a 'priority target' for the Black Cats following initial interest from the club.
Duffy, 24, may be familiar to some fans given that he was a youngster with Everton, but dropped down to the Championship in 2014 in order to play first-team football on a regular basis.
Having impressed at Ewood Park, the one-cap Republic of Ireland international is now attracting interest, and at 6ft 4in tall, he would certainly fit the mould of a typical Allardyce defender, possessing size, strength and aerial ability.
Allardyce does have the ageing Wes Brown and John O'Shea at his disposal, but they are coming to the end of their careers, whilst Younes Kaboul has done little to impress since signing from Tottenham last summer - meaning Allardyce may seek a long-term partner for the impressive one, and as Sunderland allegedly step up their interest in Duffy, he could be the man for Sunderland this summer.
Do you think Sunderland need another centre back?
