Cristiano Ronaldo and Lionel Messi have spent two decades refusing to let the other have the final word.And now, at what is surely their final World Cup, footballs defining rivalry has been given one last burst of life.Ahead of Portugal's showdown with Uzbekistan on Tuesday, Ronaldo found himself under more pressure than ever before.

The decision paid off beautifully, as the Paris Saint-Germain star executed his set-piece to double Portugal's lead.But Ronaldo wasn't done rewriting the history books. Just before the half-time whistle, he added another layer to his mythos, latching onto a sublime Bruno Fernandes pass to fire home from a tight angle.The ensuing celebrations were notably emotional, with the former Real Madrid and Manchester United icon looking visibly relieved as he was mobbed by his teammates.Watching from the ITV studio, Roy Keane bristled at the pre-match suggestions that the veteran was now a hindrance rather than a help to his nation."Why would you ever doubt him?
