6. Midfield Pivot Jack Colback (Man United Rating 5.5)
I wasn't impressed with Jack Colback against Manchester United and think that him and Vurnon Anita are Newcastle's weakest link. The 25-year-old was constantly behind the play and relied on Anita to cover him as Manchester Uniteds midfield danced through the middle. Lack of competition for the former Sunderland player's position means that Colback will be faced with the tricky role of monitoring the Gunners' flamboyant, interchanging central players.
