According to Dutch website Voetbal International, Sunderland have made an approach to sign Chelsea midfielder Marco van Ginkel this summer.
Reinforcements are needed, and Voetbal International report that Advocaat has now made an approach to sign Chelsea midfielder van Ginkel on loan.
Van Ginkel, 22, has spent the last year on loan at AC Milan, but now returns to Chelsea, where he is unlikely to be given regular first team football considering the embarrassment of riches at Jose Mourinho's disposal.
Another loan move this summer appears to be on the cards, and Sunderland are keen to take him to the Stadium of Light - despite interest from fierce rivals Newcastle.
The Daily Mail recently suggested that the Magpies were looking to sign van Ginkel - but Sunderland are now seemingly set to hijack that bid.
Newcastle or Sunderland?
With the North East rivals set to go head to head over van Ginkel's signature, which team could end up signing the player this summer?
Sunderland have a number of midfielders such as Seb Larsson, Jack Rodwell and Lee Cattermole, but van Ginkel would provide them with more quality in the final third - something Sunderland certainly need next season.
Newcastle need improvements all over the pitch, and van Ginkel could expect plenty of football under new manager Steve McClaren - and with potentially higher aspirations than the Black Cats next season, it would be little surprise to see van Ginkel choose Newcastle over Sunderland.
