Sunderland manager Roy Keane is keeping a close watch on defenders Jonny Evans and Danny Simpson as he desires to take the Manchester United duo in January transfer window.

The Black Cats boss, who had the duo on loan last season as the Wearsiders earned promotion to the Premiership, is well aware that there would be many calling up Red Devils boss Sir Alex Ferguson with the eye on Evans and Simpson.

The former Manchester United skipper told the Sunderland Echo: "Jonny, if I thought for one minute there was an opportunity to bring him to Sunderland, with the quality he's got, we would have to consider it.

"Nothing happens until January anyway because he's under contract to United. But I know there will be a lot of teams ringing up United after Sir Alex (Ferguson) said the other week that there would be plenty going out on loan.

"His phone will be red hot at this moment in time and whether Jonny will still be there in January I really don't know.

"But Jonny did brilliantly for the club, as did Danny, and it would be nice if we thought they could come back. But it's a big 'if'."

Keane added: "It was a nightmare giving them back, I have to say, because they'd settled in so well.

"But they were good professionals, hard trainers out on the pitch, half-decent with the media side and ready to put everything in."
