Newcastle United beat a weakened Millwall 1-0 in the Carabao Cup third round, with Joe Willock scoring the only goal in the 81st minute to send Steve Jaissle's side into the next round. The result offered early encouragement for Newcastle's new manager, whose vertical, transition-based playing style is still being bedded in, while Millwall's spirited display despite heavy injury problems left their own supporters satisfied with the performance even in defeat.

Jaissle fielded a strong Newcastle side, with Jacob Ramsey replacing the in-form Anthony Elanga, while Millwall's Alex Neil made seven changes to a squad missing 13 players through injury. Newcastle dominated possession and chances throughout, reaching 70% possession and 17 shots by the hour mark, but were made to work by a resilient Millwall defence and some dangerous set-piece moments before Willock's late strike settled the tie at the Den.
