Koby Arthur

Return to Birmingham A hamstring injury prevented any immediate involvement with the team, but after what assistant manager Steve Watson described as a breathtaking training session, and with Demarai Gray unavailable through injury, Arthur made his full League debut for Birmingham on 30 September 2014 in a 3–1 win at Millwall, the club's first away win of the season. He missed out on a debut goal in the next match, away to Charlton Athletic, when his attempt was disallowed for offside against Clayton Donaldson. After Gary Rowett took over as manager, Arthur had a brief run in the side, but he never broke through to the first team; his last league appearance for the club came on 6 December 2014, in a 1–0 defeat away to Blackpool. His progress was disrupted by injury, and he returned to Birmingham having made just seven appearances.

He linked up again with assistant manager Steve Watson, his former coach at Birmingham. Arthur made his debut as a late substitute in a 1–1 draw at home to Hartlepool United on 8 August. He made 14 league appearances and scored once, in a 4–1 defeat at home to Maidstone United, as Macclesfield went on to win the National League title and promotion back to the Football League. Although he was not initially included on Macclesfield's retained list, he signed a one-year deal to extend his stay with the club. On the opening day of the 2018–19 season, Arthur scored twice at home to Swindon Town, but his team lost 3–2. He made 25 appearances in all competitions,

Kidderminster Harriers Arthur had hopes of remaining in the Football League with Walsall, but an Achilles injury in a pre-season friendly was to keep him out of football for some time.

At the end of May, he signed for Kidderminster for the 2020–21 season. He made 11 league appearances before the season ended early because of issues surrounding the COVID-19 pandemic, and was released when his contract expired.

Dover Athletic After featuring for the club in pre-season, Arthur signed for Dover Athletic of the National League in August 2021.

On 15 April 2022, Arthur scored his fifth goal of the season which proved to be the winner as Dover got only their second win of the season against Boreham Wood, taking their points tally up to zero after their twelve-point deduction prior to the season. Arthur was not retained by the club following relegation.
