Smaller WXV balls have 'changed the game'

Wales back Lisa Neumann says the smaller balls being used in the upcoming WXV Global Series have "changed the game".

Women's teams will play with World Rugby's new 4.5 size balls - about 3% smaller but the same weight as a regulation size five.

Their introduction has not been without controversy and England fly-half Zoe Harrison described the move as "the worst decision ever".

But Wales' Neumann welcomes the trial.
