Watch: Leanne Kiernan and Katie McCabe on the double as Ireland cruise past Northern Ireland

Leanne Kiernan and captain Katie McCabe have both scored twice as the Republic of Ireland lead Northern Ireland 4-0 in their final World Cup qualifying game.

Both sides were already out of contention for a finals spot going into the game, which is Northern Ireland's penultimate outing, but a fourth win of the campaign never looked in doubt for Ireland.

New West Ham United signing Kiernan opened the scoring after three minutes as she bravely beat goalkeeper Jackie Burns to the ball before lifting it into an empty net.

McCabe doubled the scoring shortly after as Tyler Toland's shot was too hot for Burns to handle, and Rianna Jarrett teed up the rebound for the Arsenal winger to drill into the roof of the net.

Kiernan scored her second, and Ireland's third, before the half-hour after being played in by Denise O'Sullivan before McCabe added a second-half penalty.
