The Hoops today announced that they’d completed the signing of the Irish winger on a three-year deal.
He joins after a very impressive season personally, in which he scored 10 goals and made 13 assists as Aberdeen finishing second in the Premiership and lost to Celtic in both the Betfred Cup and the Scottish Cup.
