Ninety-two teams will compete for the chance to play in the final at Wembley Stadium in March, and 13 Premier League sides will take part in the second round this week.
But City, as well as the six other teams competing in European competition this season, won’t be involved until the third round.
Here's everything need to know ahead of that draw...
When and where does the draw take place?

What time does it take place?
In the event of a tie, all matches will go straight to penalties. This means you can expect the Cup draw to take place at around 10pm.

Ahead of the 2018/19 competition, EFL clubs voted on a number of rule changes for the competition.
No extra time
Aside from the final - which will have a total of 30 minutes extra time if required - all fixtures will go straight to penalties if they result in a draw after 90 minutes. This means that the traditional away goal rule has been abolished.
The EFL says removing an additional 30 minutes will “directly address any additional fatigue issues,” because sides also have to play a league fixture in the same week.
Seeding was removed from the initial two rounds of the Carabao Cup.
Five bookings in all domestic competitions used to result in a one-match ban. Now, the ruling has been amended to exclude League Cup cautions, which will only be relevant to that competition.
