Callum Anthony Reilly (born 3 October 1993) is a footballer who plays for Birmingham City and the Republic of Ireland under-21 team. A midfielder who has also played at full back, he made his first-team debut in January 2012 in the fourth-round FA Cup-tie against Sheffield United.
Reilly was born in Warrington, Cheshire, and raised in Solihull, West Midlands, where he attended St Peters Catholic School. He joined Birmingham Citys youth system at the age of seven,and began a two-year scholarship in July 2010.
He was given a first-team squad number in January 2012, and his first competitive involvement came when he was named among the substitutes for the third-round FA Cup-tie against Wolverhampton Wanderers, remaining unused. Reilly made his first-team debut on 28 January, coming on as an 80th-minute substitute for Jordon Mutch in the fourth-round FA Cup-tie against Sheffield United at Bramall Lane, with Birmingham already 40 ahead.
He signed his first professional contract, of one year, before the 201213 season, and was given a squad number before the visit to Millwall in October.
With Hayden Mullins suspended and Jonathan Spector injured for the visit of Crystal Palace on 15 December,Reilly made his first start, and first appearance in the Football League, alongside Papa Bouba Diop in central midfield. He played the full 90 minutes as Birmingham came back from 20 down to draw. On his sixth Championship start, a 11 draw away to Huddersfield Town, Reilly "swept in" a knock-back from Chris Burkes cross in first-half stoppage time to score his first senior goal. He was substituted at half-time due to illness. In April, the club took up their option to extend Reillys contract for another year. He ended the season with 18 league appearances, and signed a new two-year contract ahead of the 201314 campaign.
Ahead of the 201314 season, Reilly scored with a deflected shot in a 40 friendly victory against Shamrock Rovers.
Reilly received his first call-up to the Republic of Ireland under-21 team for a friendly match against the Netherlands on 6 February 2013. He was selected in the starting eleven, and played 64 minutes before being substituted, as Ireland won 30. On his second appearance, he played the first half of a 21 home defeat to Portugal in March. He had a chance of scoring on his first competitive appearance for the under-21s, in a European under-21 championship qualifier away to the Faroe Islands, but his shot was well saved; Ireland won 41.
