Daniel Kelly, born on 3 October 2005 (age 21), is a Scottish centre midfielder who came through at Celtic before moving south to Millwall. His Celtic senior record was brief but not empty: in 2023-24 he made four league appearances and scored once, a small glimpse before his career took its main turn elsewhere.
Kelly left Celtic for Millwall in August 2024. That move has shaped his senior career so far, with Millwall giving him the bulk of his football: 20 league appearances across three seasons. In 2026-27, he has made nine Championship appearances and three more in the League Cup, taking him to 12 appearances in all competitions for the season.
He wears squad number 48 at Millwall, and his current market value is around £595,000, according to Transfermarkt. His story is a familiar one: developed at Celtic, moved on early, and now building a professional career in England with Millwall as the central chapter to date.
