The Carabao Cup semi-finals continue tonight with Nottingham Forest welcoming Manchester United at the City Ground.
The winner of the tie will face either Newcastle United or Southampton in the final at Wembley on February 26.
With the regulations changing from one competition to another, here is your full lowdown of the rules in play across the semi-finals of the Carabao Cup 2023.
Are the Carabao Cup semi-finals played over two legs?
Yes, the Carabao Cup semi-finals will take place over two legs.
Newcastle beat Southampton 1-0 in the first leg of the first semi-final on Tuesday night, with the return leg scheduled for Tuesday, January 31 at 8pm.

Meanwhile, Manchester United will host Nottingham Forest in the second leg of their semi-final on Wednesday, February 1 at 8pm.
VAR is in use for the first time in the Carabao Cup this season, having not featured in earlier rounds to ensure fairness across every tie.
Will extra-time and penalties be used in the Carabao Cup semi-finals?
If the score is level after the end of both legs then extra-time, and if required penalties, will be used to determine the winner.
This is the first time this season that matches finishing level in the Carabao Cup will head to extra-time, with ties previously proceeding straight to penalties in the event of a draw after 90 minutes.
The away goals rule will also not be in use for the two semi-finals.
The English Football League scrapped the rule ahead of the 2018/19, which up until that point only came into effect following the conclusion of extra-time.
How many substitutes are allowed in the Carabao Cup?
Managers will be able to use up to five substitutes across three windows during the game (half-time not included).
An extra substitution is permitted in extra-time, whilst both teams can also use two concussion substitutes if required.
