Centre-half Liam Scales believes Celtic's late run to a league and cup double means they can go into the next season "on a positive note" while also realising they cannot rest on their laurels. Celtic improved in Martin O'Neill's two spells as interim manager and ended the season beating second-tier Dunfermline Athletic 3-1 in Saturday's Scottish Cup final - a week after retaining the Premiership title by beating long-time leaders Hearts by the same scoreline. "It gives us that chance to go into next season on a positive note," 27-year-old Republic of Ireland international Scales said.
