Christensen went down theatrically to win the freekick leading to Denmark's goal, that could have decided the game but, England didn't let it. Danes could had time to come back after a poor call but, couldn't. England were also in the ascendancy at that point, I mean they had just let Sterling that deep into their own penalty area and that was becoming the norm at that point in the game. Chances were high England would have continued in that vein and a goal was looking likely anyway.
Better team went through, on a dodgy call for a penalty but, hardly a historical moment of cheating
