The fourth round of the Carabao Cup has thrown up some eye-catching clashes, which could be forced to be decided after the 90-minute mark.
Among the all-Premier League clashes in the fourth round is Manchester City's clash with Southampton at the Etihad Stadium, one of five matches taking place on Tuesday evening.
The Carabao Cup underwent a number of rule changes for this season's competition, but what happens if games in round four finish level after 90 minutes?
Will there be extra-time, or will games go straight to penalties? Here's all you need to know.
Carabao Cup rules on extra time and penalties
No extra-time will be played in the Carabao Cup fourth round. The tournament decided to scrap extra-time ahead of the 2018/19 season to help reduce player fatigue.
Ties will instead go straight to a penalty shootout.
The Carabao Cup used the ABBA format during the 2017/18 campaign but reverted back to the traditional shootout format last season, which will continue to be the case this term.
Article 14.4 of the Carabao Cup’s rulebook states: "In the event of the scores being level at the end of ninety minutes’ play in Rounds One, Two, Three, Four and Five no extra time shall be played, and the winners shall be determined by the taking of kicks from the penalty mark in accordance with procedures as approved by IFAB."
The semi-finals will also follow the same format but the Carabao Cup final will observe a period of extra-time should the Wembley showpiece end in a draw.
Article 14.5 reads: "In the Semi-Final ties, if the aggregate score is level at the end of the second game no extra time shall be played and the tie shall be decided by the taking of kicks from the penalty mark in accordance with procedures as approved by IFAB.
"If the score is level at the end of ninety minutes in the Final Tie an extra half hour shall be played and if the score be still level at the end of extra time the winners of the Competition shall be determined by the taking of kicks from the penalty mark in accordance with procedures as approved by IFAB."
