Manchester United were held by Newcastle United in a pulsating match. Javier Hernandez gave United an early second-half lead after Wayne Rooney's volley ricocheted off Steven Taylor before then hitting the Mexican. Newcastle drew level from a disputed penalty after Rio Ferdinand was ajudged to have fouled Hatem Ben Arfa with Demba Ba scoring from the spot-kick. Jonas Gutierrez was then sent off, Tim Krul made two great saves, Ashley Young hit the post, but the Magpies held on. The draw leaves the champions four points behind rivals Manchester City, who travel to Liverpool on Sunday. That Newcastle left Old Trafford with a point had much to do with Krul's superb goalkeeping performance and the visitors' ability to throw bodies in the way of the ball in a frantic 12-minute period after Gutierrez's dismissal. Krul somehow got his body in the way of Nemanja Vidic's fierce header and then pushed away Patrice Evra's shot while Danny Simpson typified Newcastle's resilience when he cleared a Hernandez effort off the line. At times in that thrilling conclusion Krul's goal seemed to be protected by a magnetic forcefield as Ashley Young rattled the post with a shot, while a last-gasp Hernandez goal was ruled out after the Mexican strayed offside when he poked home Ryan Giggs's cross. If Newcastle rode their luck at times it was also a performance that adds to the growing body of evidence that the Magpies can continue to prosper this season after their fine start with this draw keeping them in fourth. In the opening half Alan Pardew's side had looked to attack at every opportunity with Ben Arfa and Gabriel Obertan effective in creating chances with their vision and touch - both from the centre of the pitch as well as the flanks. Ben Arfa produced the cutest of passes with the outside of his foot to scoop the ball over the United defence to Ba, whose volley tested David de Gea. A cross from Obertan, who was arguably the visitors most effective player in that first half, created Newcastle's best chance with a cross from the right, but Ryan Taylor miscued with his volley. However, that Newcastle went in at the break level was primarily to do with Krul's reactions. Early on he saved twice from Hernandez before the Dutchman flung himself to his right to produce a fingerip save from the deftest of flicks from Giggs. Just before the break Newcastle were handed a reprieve when Hernandez miscued with a shot when he probably should have scored. Strangely prior to Saturday, Hernandez had not scored at Old Trafford this season, and he was to know little about the goal that ended that run on 49 minutes. Steven Taylor had fouled Hernandez to win a free-kick just outside the box and although the Newcastle wall blocked Rooney's set-piece shot the England striker was quickly onto the rebound. Rooney's volley went deep into the Newcastle area before ricocheting off Steven Taylor and then off Hernandez into the net. It was a desperately unlucky way to go behind, but the visitors were soon to profit from a contentious penalty that was awarded when Ben Arfa went down after a Ferdinand tackle. Television replays appeared to show the United defender had won the ball cleanly but referee Mike Jones after consultation with his assistant awarded the penalty that Ba slotted in as De Gea went the wrong way. The Manchester United goalkeeper produced a wonderful save to parry a Fabrizio Coloccini effort, but once Gutierrez had been dismissed Newcastle had only the manpower to concentrate on defending their goal.
