Cristiano Ronaldo converted one penalty, missed another and also scored from open play as Portugal beat Latvia 4-1 in their World Cup qualifier. Yesterday on a typically dramatic night for the Portugal captain, Ronaldo fired the European champions ahead from his first spot kick of the evening in the first half, but missed a chance to double their lead when his second effort struck the post.It looked a costly miss when Arturs Zjuzins equalised for Latvia in the 68th minute but William Carvalho headed Portugal back in front two minutes later, Ronaldo volleyed the third and Bruno Alves completed the win.
