The 2014-15 campaign delivered a domestic double for Celtic as The Bhoys, under new manager Ronny Deila, surged to their fourth consecutive Scottish Premiership title and won the Scottish League Cup. Leading the charge was the prolific forward Leigh Griffiths, whose 14 league goals (20 overall) proved decisive in a campaign built on a record-setting defensive masterclass that conceded only 17 goals all season. It was a standout year that, despite early European struggles, saw a mid-season turnaround, epitomized by the birth of the 'Ronny Roar' celebration, and secured the club's continued domestic dominance.
