Manchester United were the defending champions, but they were eliminated by Bristol City in the fifth round.

There were plans for the 2017–18 EFL Cup to trial video assistant referees during matches in their first use in England.

There were a number of errors in the draw for the first round. Many fans experienced problems with the sound on the live stream from Thailand, and had to rely on the graphics. However, these contained a number of errors: Charlton Athletic were shown to be drawn in two ties, while a number of other teams including AFC Wimbledon, Brentford, Swindon Town, Norwich City, Forest Green Rovers, Wolverhampton Wanderers and Yeovil Town were all shown to have been given wrong draws. The English Football League later issued a statement apologising for the errors that had been made and stating that the draw had not been compromised with all clubs receiving confirmation of their ties.Confusion also arose over the televised portion of the second round draw, in which four second round matches were announced with the incorrect location. The cup attracted even further criticism for its draws when it was announced that the third round draw would take place in Beijing at 11:15 China Standard Time.
Further errors continued for the draw of the fifth round. This was due to technical problems at Twitter, which led to the draw being delayed for over an hour. The draw finally appeared in a pre-recorded video almost two hours late.
