The central midfielder has been with the Reds since the age of 10 and has captained sides throughout various age groups.
Coyle, 20, is renowned as a tough tackler who patrols the area in front of the back four, breaking up play and setting up counter-attacks.
A passionate boyhood Red, Coyle used to walk to training sessions at Melwood from his home in West Derby just 10 minutes away.
He made his debut for the U18s as a 15-year-old and has since progressed to the U23 squad.
Internationally, he has been called into the Northern Ireland U21 setup, though a persistent back problem has limited his appearances in recent times.
