Millwall Football Club has officially signed 18-year-old midfielder Daniel Kelly from Celtic for an undisclosed fee, with reports suggesting a deal worth nearly £400,000 plus add-ons. Kelly, who had been with Celtic since childhood, made six first-team appearances last season but opted to leave after declining a new contract. Director of football Steve Gallen emphasized that Kelly's athletic and dynamic playing style aligns perfectly with the club's vision of developing young talent. Although he was unable to join the squad for Millwall's upcoming match against Hull due to a paperwork delay, the club is optimistic about his future contributions. Head coach Neil Harris noted the importance of patient development for Kelly, likening his potential to that of other young players that have thrived at the club. The signing marks Millwall's seventh addition in the transfer window, underscoring their commitment to building a sustainable and competitive team.
