John Andrew O'Kane (born 15 November 1974) is an English former professional footballer who played as a defender.
He started his career with Manchester United but failed to break into the first team, and after loan spells with Wimbledon, Bury, Wrexham and Bradford City,[1] he made a permanent move to Everton in January 1998.
He began his professional career at Manchester United in 1990 and played 7 competitive games for the club before signing for Everton in January 1998.
He had a brief loan spell at Wimbledon in 1995, featuring in their makeshift squad for the 1995 UEFA Intertoto Cup along with fellow United players Michael Appleton and Graeme Tomlinson.
He was finally sold from Old Trafford after refusing another contract, in the 1997–98 season for a fee around £1 million, 14 months after his last appearance, when Howard Kendall signed him for Everton.
