Manchester United defender Jonny Evans has warned his team-mates to be wary of the threat posed by Newcastle despite the Tynesiders dip in form this season.
The two sides face each other at Old Trafford on Boxing Day with the home side top of the Premier League and the Magpies down in 15th place.
But Evans insists Newcastle striker Demba Ba and Papiss Cisse still pose a threat as Alan Pardew's charges look to regain the form that saw them secure a Europa League place this campaign.
"Those guys are both very powerful. What Newcastle do very well is work the ball wide and put it in the box," said the Northern Ireland international.
"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."
Sir Alex Ferguson's side have already beaten Newcastle twice this season, including a 3-0 win at St James' Park in October.
Evans was among the scorers that day and he believes that impressive victory is indicative of their improved away form this campaign.
"In the last couple of seasons we have gone away to places like Newcastle and either lost or drawn," added Evans.
"This time it was very important to win. We were well prepared, had the right mindset and defended well.
"With the goals as well it was one of our best performances of the season."
