Maria Sharapova and highly rated teenager Eugenie Bouchard have shared a sponsors' photo-shoot, but the Russian superstar pledged no favors when the pair meet for a place in the French Open last 32.

Sharapova, the defending champion and world No 2, and 19-year-old Bouchard, last year's junior Wimbledon winner, are both on Nike's books with the Canadian youngster even wearing on-court clothing designed by the Russian.

However, Sharapova intends to put the world No 77, who won her maiden Grand Slam match on Monday, firmly in her place when they meet for the second time this year.
