Celtic chairman Ian Bankier believes that new manager Ronny Deila will bring "great success" to the Scottish champions after being appointed as Neil Lennon's successor.
The 38-year-old, who guided Norwegian side Stromsgodset to title glory last season, has signed a 12-month rolling contract at Parkhead.
Bankier told the club's official website: "We are delighted to have secured Ronny as Celtic manager. He is a highly-regarded individual and a man who we are confident will bring great success to Celtic.
"He is a forward-thinking coach and manager with a progressive approach. The Celtic board will support Ronny fully and in every way and we look forward to working with him."
Celtic chief executive Peter Lawwell added: "We believe Ronny will prove to be a fresh and dynamic new manager and someone who will give us a bright and energetic way forward for Celtic.
"Ronny likes to play attacking, winning football, the Celtic way, something I know our supporters will endorse. As the new season begins, I am sure our fans will get right behind Ronny and the players once again as we aim to bring success to Celtic and continue to deliver a club they can be proud of."
Lennon resigned from his post last month after guiding the champions to three league titles and two Scottish Cups over four years.
