Seems he was keen to stay at Pittodrie,but we werent keen to give him a 4 year deal,from AFC tweet below,
"Jamie McGrath will leave Aberdeen at the end of the season following the expiry of his contract. We were informed by fellow Premiership side Hibernian that he has signed a pre-contract agreement with the Edinburgh club. Both Jamie, who will miss the rest of the season through injury, and his representative made it clear he was happy at Pittodrie, and was keen to stay, but we were not prepared to offer him a four-year extension. Everyone at Aberdeen FC respects Jamieās decision to look elsewhere, thanks him for his time at the club and wishes him all the best for his future career.Jamie McGrath will leave Aberdeen at the end of the season following the expiry of his contract.
