The draw for the third round of the Carabao Cup will take place on Wednesday night – but organisers have been forced to do it in two stages.

Cambridge, Port Vale and Bradford are among the clubs in the draw after taking scalps from higher leagues on Tuesday night. They are three of the 32 sides who will play third round fixtures on the weeks beginning September 15 and September 22.

There are still four second round ties to take care of on Wednesday night, with Grimsby hosting Manchester United the pick of the games. But it isn’t the fact that the previous round isn’t complete that complicates the draw.

Instead it is the Champions League and Europa League that has forced the EFL to alter the way they will conduct the draw. The Carabao Cup schedule overlaps with those of UEFA’s top two club competitions and they take precedence over the domestic cup competition.

To avoid any clashes, clubs taking part in the Champions League or Europa League will be kept apart in the third round. There are nine Premier League sides competing in Europe this season, with eight of those in the Champions League and Europa League – a significant number of the Carabao Cup's competitors.

In order to make it viable and ensure the ties don’t clash, the EFL have decided that a pre-draw will be conducted before Grimsby vs United. That will decide whether the eight sides involved in the Champions League or Europa League will be drawn at home or away.

Those sides are Arsenal, Manchester City, Liverpool, Chelsea, Newcastle, Tottenham, Nottingham Forest and Aston Villa. They will be drawn against eight teams who are not competing in Europe, before the other eight ties will be drawn in the normal fashion.

Having been split into northern and southern sections for the earlier rounds, the geographical aspect will now disappear.
