Ferguson feels Keegan has a difficult job.
Sir Alex Ferguson: "It is not easy getting players in January. That was really Kevin's problem.
"He has not really had time to get those in he wanted. He's had to rely on the players he's got.
"I haven't spoken to Kevin for ages. He was out of the game for three years of course. I am looking forward to seeing him.
"People go about mind games and get carried away with it. It is an over-played thing.
"Although our record is decent at Newcastle, we don't take things for granted.
"We expect a hard game as Kevin will be determined to try to get a result."
