Aaron Osborne is a goalkeeper from Cromer who played in a number of Norwich's friendlies in the summer of 2001 including the first team clash with Fakenham.

Aaron became an Academy Scholar at Carrow Road in 2001. He was named goalkeeper of the tournament in the prestigious international Doetinchem Tournament where Norwich finished third in August 2002, beating FC Copenhagen for third place. Other participants included Anderlecht, Ajax and a USA representative side. He played for the reserves during 2002/03.

At the end of November 2003, Norwich announced that they would not be giving Aaron a professional contract. He joined Oxford United on a two-week trial but by early December, was playing for Great Yarmouth Town in the Ridgeons Football League. Yarmouth manager Paul Tong said "He needs games to maintian his form. I coached him as a youngster at Norwich and though I have been criticised for playin ghim last week in view of the big FA Vase match (Vs Cray Wanderers) coming up, I thought he was worth having a look at, and I'm always looking to the future of the club"

Aaron was invited to a trial with Bristol Rovers in February 2004 alongside fellow Academy players Greg Crane, David Chick and David Tyrie.

Aaron moved from the East Coast to West Norfolk on 15th June 2004 signing for Kings Lynn. He quickly declared that he would be fighting for the Number One shirt against Stevie Wilson. In November 2004, Aaron left Lynn to join North Norfolk side Cromer.
