Hansen wrote in the Telegraph: "Any aspiring centre-half should get a DVD of the Spurs game and watch the way those two played.
"You would not fail to learn the basics of defending, getting into the right positions and reading the game. They have such an intuitive understanding and when Vidic steps left, Rio will step right. United’s goal was excellent but the Spurs back four were simply pulled apart for it. In an identical situation for Spurs, they just could not find a way past Rio and Vidic.
"It will be difficult to keep them playing together all season but the more Sir Alex can do it, the better United’s chances of winning the title will be. They deserved get three points – but the reason they did not is because of the goalkeeper, and its something United have got to deal with or it could end up costing them."
