Joe Willock scored a late winner as Newcastle United survived a scare against Championship side Millwall to reach the last 16 of the Carabao Cup.
Newcastle head coach Matthias Jaissle showed his respect for injury-hit Millwall, and the competition, by naming a strong team for the third-round tie at the Den.
However, the blunt visitors struggled to fire in front of goal and a penalty shootout was looming until Willock turned Lewis Hall's drilled cross into the net in the 81st minute.
The breakthrough came after Millwall substitute Tairyk Arconte saw a drilled effort cannon back off the post after he capitalised on some slack defending from Tino Livramento to run through on goal.
For all the possession Newcastle enjoyed, the 2025 winners mustered just a single shot on target in the opening hour when Willock saw a venomous effort beaten away by Millwall goalkeeper Filip Marschall at his near post.
Newcastle did have a strong penalty appeal waved away on the stroke of half-time, though, after Millwall defender Caleb Taylor pulled Fabian Schar's shirt inside the box.
The Premier League side eventually found a way past spirited Millwall to progress into the fourth round as Jaissle maintained his unbeaten start.
