Transfermarkt calculates a player's market value using a qualitative approach and says the goal is to estimate the value of a player in a free market, not to predict a specific transfer fee.
While some of the numbers can be skewed, it’s still a good indication of who they rank as the Irish League’s most exciting talents and those that could potentially be set for bigger and better things in the future.
Using their market values system, here are who they view as the Premiership’s top 15 most valuable young players aged under 21.
5. Dylan Sloan (Larne)
Dylan Sloan has been a proven performer for Larne on both the European and domestic fronts this season and was recently rewarded with a long-term contract at Inver Park. The 20-year-old celebrated by scoring twice in Friday's 2-0 league win over Cliftonville and has previously been linked with a move across the water. Photo: Andrew McCarroll/Pacemaker Press
6. Jacob Blaney (Crusaders)
Former Hibernian defender Jacob Blaney arrived in the Premiership with Crusaders during the summer and has played his part in 22 of their 24 league matches this season. The 20-year-old will only continue to improve at Seaview under the watchful eye of Declan Caddell. Photo: David Maginnis/Pacemaker Press
7. Adam Towe (Loughgall)
Adam Towe came through the youth ranks at Dungannon Swifts before joining Loughgall and the 19-year-old has had an opportunity to gain significant senior experience at Lakeview Park. He has played 21 times in the Premiership and scored a memorable first goal against Ballymena United last month. Photo: Alan Weir/Pacemaker Press
8. James Douglas (Glentoran)
James Douglas has shown maturity beyond his years after breaking into the Glentoran first team this season, making 16 Premiership appearances for Declan Devine's side and scored a memorable BetMcLean Cup winner against Linfield. Still only 18, Douglas has already been rewarded with a new long-term contract. Photo: Glentoran FC
