Oliver Luke Arblaster (born 8 January 2004) is an English professional footballer who plays as a midfielder for EFL Championship club Sheffield United.
[17] David Flitcroft, the club's director of football, said that "he is a player that has great potential ahead of him we would like to thank Paul Heckingbottom of Sheffield United for entrusting us with the further development of him".
[18] He made an immediate impact to the 2023–24 season, being named as the club's Player of the Month as he "played a key role in the engine room of a Port Vale side that accumulated 10 points throughout August".
[20] On 11 November, he received the first red card of his career after being sent off following a second booking offence for a reckless late challenge on Ethan Erhahon in a 1–1 draw with Lincoln City.
[21] On 19 December, he was stretchered off with a badly-gashed knee during the second half of a 3–0 defeat to Middlesbrough in the quarter-finals of the EFL Cup and was ruled out of action for an undetermined period of weeks.
[22] Ten days later, it was confirmed that he had been recalled back to Sheffield United, with new manager Chris Wilder reportedly keen to play him once he returned to fitness.
[31] In November 2021, Arblaster was called up to the England under-18 squad by head coach Neil Ryan for the Pinatar Tournament in Spain, featuring against Belgium.
