Paris: Reigning Ballon d'Or Aitana Bonmati scored one goal and helped create another as World Cup holders Spain came from behind to beat Japan 2-1 in their first game of the women's Olympic football tournament on Thursday.

Spain's starting XI featured seven players who were in the line-up for last year's World Cup final win over England in Sydney, plus Alexia Putellas, the two-time former Ballon d'Or winner.

They then grabbed the winner when Caldentey came in from the left and exchanged passes with Bonmati before firing in.
