According to the Daily Mirror, Sunderland will make a move for PSV Eindhoven striker Jurgen Locadia, should they fail to sign Fenerbahce forward Moussa Sow.
Advocaat has added the likes of Sebastian Coates, Younes Kaboul, Adam Matthews and Jeremain Lens already this summer, but a move to sign a striker has to be a priority.
Steven Fletcher, Danny Graham and Connor Wickham all struggled to find the back of the net last season, and The Mirror report that Fenerbahce forward Sow is Advocaat's top target.
Yet with the Turkish side keen to keep Sow, the report also states that Advocaat is also interested in a reunion with PSV Eindhoven striker Jurgen Locadia, having worked together during the 2012/13 season.
The 21-year-old striker, who scored 11 goals in 22 games under Advocaat, hit nine goals last season, a comedown from his 17-goal campaign in 2013-14.
Locadia is a big, physical striker who possesses strength and enough pace to trouble defences in behind as well, making him an intriguing prospect for the Black Cats.
The Dutchman appears to be a fallback plan in case Sunderland can't secure the signature of Sow, but his familiarity with Advocaat and his methods could even make him a better option - especially considering he is eight years younger than Sow.
