John Oster

John Morgan Oster (born 8 December 1978) is a football coach and former professional player who played as a midfielder. Oster was a product of the youth team at Grimsby Town where he was added to the first team squad in 1994, however he didn't make his debut until the 1996–97 season. His performances that season caught the eye of Premier League side Everton who paid £1.5 million for him during the summer of 1997. Two years later he was sold to Sunderland where he remained until 2005.

Whilst with The Black Cats he spent time on loan with Barnsley before returning to Grimsby for two separate loan spells during the 2002–03 season, in his time back at Blundell Park he was unable to save the club from relegation. He later moved on loan to Leeds United before joining Burnley permanently.
