Newcastle have conceded three headers already this season so will be wary of the attacking threat Manchester United possess. With the likes of Juan Mata, Adnan Januzaj, Memphis and Wayne Rooney likely to be the home side's attacking four on Saturday you might be asking yourself 'what do The Magpies have to worry about?' Well, set pieces will play a huge part in the game - as they always seen to do - and Chris Smalling will be the main threat from Steve McClaren's perspective. The Englishman has found his feet at Old Trafford and has emerged as the leader of the Red Devils' defensive unit. Could you have imagined saying that a couple of years ago? Nevertheless, the centre back will be the main aerial threat for the home side on Saturday, and will be confident of profiting against a defence that is one of the smallest in the Barclays Premier League. Both Fabricio Coloccini and Chancel Mbemba are 6 ft and under, respectively, and have both been caught out already this season. Winning the aerial duels should be close to the top of the list of priorities for Newcastle. If they can't do that, it will be a long afternoon as the home side are so much more dangerous in other areas of their play.
