Sheffield United boss Chris Wilder has refused to discuss a move for Iliman Ndiaye.
The former Blades striker is being linked with a loan return from Olympique Marseille.
But ahead of tonight's clash with Aston Villa, Wilder said: : "I'm not prepared to talk about anyone; I'm focusing on the group we've got.
"Everyone knows his history here and me more than anyone, because he was a young player in my time and training with the team all season.
"From a distance I saw the effect he had on the team in his breakthrough season. He's a fabulous player, an outstanding player. But in terms of speculation, I don't want to get involved in that."
