Although he had hoped to "skip the loan stage this time and break straight through" at Manchester United, Lingard joined Birmingham City on a month's loan on 19 September, and went straight into the starting eleven for the Championship match against Sheffield Wednesday at St Andrew's two days later. He opened the scoring after 20 minutes with his first goal in senior football when goalkeeper Chris Kirkland parried Chris Burke's shot, completed his hat-trick 13 minutes later, and scored a fourth in the second half to secure a 4–1 win. Lingard was unavailable for Birmingham's League Cup third-round tie because Manchester United did not want him cup-tied, then in his third league match, he made up for missing a penalty, awarded when he was fouled apparently outside the area, with an 89th-minute header to complete a 4–0 defeat of Millwall. Agreement was reached to extend Lingard's loan until 14 December, but he then missed three matches while receiving treatment at Manchester United for a knee injury. The loan was further extended, to 1 January 2014, but Lingard was suspended for the last two matches of the spell. Against Wigan Athletic on 26 December, he was sent off for a lunge on Jordi Gómez immediately after being refused a free kick when he appeared to be fouled.
