Both Mansfield and Oldham were given a huge incentive to get through the tie, when the FA Cup draw was made at the weekend.
With Liverpool having played both sides in last years competition, it threw up an interesting twist, with the Latics knocking the Premier League giants out of the cup last season.
A Sam Clucas goal meant the Stags were able to draw 1-1 at Boundary Park for the right to have another go at Oldham, and the chance to face Liverpool in the next round.
