The 18-year-old scored the only goal of the game to give his side victory in the Manchester derby on Sunday, taking his career tally to five goals in eight senior appearances.

Beckham offered his congratulations to Rashford in an Instagram post, saying that it is "refreshing" to see a youngster playing with such excitement.
