4. Ryan Harley

The then 26 year old couldn't be classed as a "prospect" due to his age but he was well admired by his former club and appeared ready to make the step up. Harley was instantly sent back on loan to Exeter as part of the deal and the midfielder found himself returning to a newly crowned Premier League team the following season. Was this his time to make an even bigger step up to the Premier League? No, apparently not, and Harley was sold to Brighton at the start of their maiden season before his name was even printed on a Swansea shirt.
