Round Four of the Carabao Cup will see Barnsley/Chelsea face either Leyton Orient or Tottenham Hotspur away from home.
The Round Four draw was made on an either/or basis as the Round Three fixtures will not yet have been completed. This is to help enable the EFL, Clubs and broadcasters to plan with additional clarity over a busy period of fixtures.
Round Three ties will take place week commencing 21 September with Round Four being played the following week commencing 28 September.
