Newcastle showed maturity to overcome a raucous atmosphere and spirited opponent in Millwall to reach the fourth round of the Carabao Cup, says Joe Willock. Matthias Jaissle named a strong team for the third-round tie at The Den but struggled to fire in front of goal and a penalty shootout was looming until Willock found the net nine minutes from time. "I think it was a good game," the 27-year-old told BBC Radio Newcastle.
