After victory over West Ham United, Sunderland boss Martin O'Neill confirmed that Senegal international defender Kader Mangane is heading for Wearside.
Mangane will move from Al Hilal.
He said: "I'm hoping that he's making his way over at this minute. I'm not sure that anything has been absolutely and utterly completed, but it would be a loan until the end of the season.
"Of course, we have a number of positions we would like to try to fill between now and the end of January, and I'm hoping something might materialise.
"But there's a long bit of distance to go yet."
