Did James Rodriguez dive to win Real Madrid’s penalty?

Real Madrid have made a fine start to the second leg of their Champions League semifinal at home against Juventus, and have broken the deadlock on the night midway through the first half. James Rodríguez was knocked over in the penalty area by Giorgio Chiellini, affording Cristiano Ronaldo the chance to step up and score from the spot. Of course, he did. The question, however, remains: Should the penalty have been awarded? James certainly went to ground rather easily. The goal means the tie is 2-2 on aggregate, but Madrid have the advantage on away goals.
