John Morgan Oster (born 8 December 1978) is a football coach and former professional player who played as a midfielder.
It transpired that he had made the wrong move though,[citation needed] as he was rarely utilised in his favoured winger's role, in a 4–4–2 formation.
[citation needed] His low point at the club was when he was involved in an incident that ended the career of reserve player Mark Maley by accidentally shooting him in the eye with an air rifle.
Oster was released by Sunderland in January 2005,[7] shortly after returning to the Black Cats in disgrace from a loan at Leeds United,[8] where he scored once against Millwall.
[9] There was little doubt that Grimsby would have liked Oster back[citation needed] but could not afford him and their financial position and reduced league status made it an unattractive option for the player.
[citation needed] Following a short spell at Burnley,[2] where he scored once against Coventry,[10] Oster joined Reading on 2 August 2005.
[18] Due to his impressive form in the 2009–10 season,[citation needed] Rovers offered Oster the opportunity to renew his contract with the club.
Oster was an ever present for Doncaster in the 2010–11 season after topping the Rovers' appearance chart in mid April with 38 starts.
[24] Oster made his debut for Wales as an 18-year-old in 1997, coming on as an injury-time substitute for Robbie Savage in a World Cup qualifying defeat in Belgium.
[25] Oster did not play in any games under John Toshack following his appointment in November 2004, his last cap for Wales being the 2–2 draw with Northern Ireland in 2004 under previous boss Mark Hughes.
[27] In April 2002 whilst at Sunderland, Oster accidentally shot reserve team player Mark Maley with an air-gun.
