Swansea manager Russell Martin says the better team lost after Sam Bell's extra-time winner secured Bristol City's passage into the FA Cup fourth round.
The Championship rivals couldn't be separated following 180 minutes of football across the borders with both tightly-fought contests finishing 1-1 in normal time. With the prospect of penalties looming, Bell latched onto Andy King's pass to surge into the area and set up a home tie with West Brom in the next round.
The first-half of Tuesday's replay had little goalmouth action for both sides as City played a patient game by sitting back and waiting for the hosts to attack. Swansea dominated the ball with 65 per cent of the possession but rarely threatened to test Max O'Leary with any meaningful efforts on goal.
