Alan Pardew's men secured only their second win in 12 games with an unconvincing display against QPR on Saturday.
Whereas last season they were scoring goals for fun, this time around it has been far harder, and rather than challenging for a Champions League spot, they have been nervously looking over their shoulders at the drop zone.
But Evans does not feel that is a reason for Manchester United to take it easy at Old Trafford on Boxing Day.
The Northern Ireland international knows Senegal duo Demba Ba and Papiss Cisse can cause problems for any defence.
"Those guys are both very powerful," said Evans.
"What Newcastle do very well is work the ball wide and put it in the box.
"A lot of their goals come that way because Ba and Cisse don't give you a minute.
"When the ball is floating around in the box, they beat people in the air and their goal record is what got Newcastle to where they were last year."
