Leighton Clarkson has signed for Aberdeen from Liverpool for an undisclosed fee after the midfielder's year-long loan at Pittodrie.
The 21-year-old, who has signed a four-year contract, made 38 appearances, scoring six goals, as the Dons finished third in the Scottish Premiership.
Clarkson came through the Liverpool youth ranks and made three first-team appearances before being sent on loan.
His first port of call was local club Blackburn Rovers in summer 2021.
After playing seven times for the Championship side, he next headed to Pittodrie, where he quickly became a fans favourite by scoring on his debut and finding the net three times in his first six outings.
