Sunderland will reportedly battle with Newcastle United for the signature of Ajax midfielder Vurnon Anita.
The 23-year-old is expected to leave Holland this summer, and it was understood that Newcastle were leading the chase.
However, Black Cats boss Martin O'Neill has expressed an interest, according to Sky Sports News, and could move before the start of the season.
The Dutchman will reportedly close in the region of £10m.
