Willy Gnonto and Patrick Bamford both struck twice as Leeds thumped Cardiff 5-2 in their FA Cup third-round replay at Elland Road.
Gnonto gave Leeds a flying start with a stunning volley inside the opening minute and fired home his second after Rodrigo had struck his 11th goal of the season to put his side 3-0 up before the interval.
Substitute Patrick Bamford then bagged a second-half double before Callum Robinson scored two late consolations for Cardiff, the second a penalty, as Leeds reached the fourth round of the competition for the first time in six years.
Leeds scored five goals for the first time since beating West Brom 5-0 in December 2020 and now face an away tie at Accrington or Boreham Wood.
A stoppage-time equaliser from Leeds teenager Sonny Perkins salvaged a replay at the Cardiff City Stadium 10 days ago, but the managerless Sky Bet Championship strugglers were put to the sword before half-time.
