Scottish champions Celtic have appointed Norwegian Ronny Deila as their new manager, following the departure of Neil Lennon last month.
Deila guided Norwegian Stromsgodset to the Tippeligaen title last season and won the Norwegian Cup in 2010.
"I will treasure this opportunity and will give everything I have to achieve success for Celtic," said Deila.
"It is a magnificent honour to be named the new manager of Celtic, one of the world's great football clubs and a club I have such enormous respect for."
"I know what I want for Celtic and our supporters and that is the best of everything, it is what our fans deserve."
"I want to deliver the best attacking, exciting and entertaining football we can play, for the players to give their best every time they take to the field of and, of course, I want my players to work with me to achieve the best results possible and bring trophies to Celtic."
"Celtic is in great shape and the club has enjoyed real success in recent years due to the hard work of Neil and his team. I want to carry on this work and continue to bring happy times to Celtic. I can't wait to get started on this journey."
Deila took charge of Stromsgodset in 2008 following a period as a player and assistant manager at the Drammen club.
He leaves with Stromsgodset sitting second in Norway's top flight, five points behind Molde, but his farewell was a disappointing 4-2 loss to second-tier outfit Tromsdalen in the Norwegian Cup on Wednesday.
Celtic chief executive Peter Lawwell told the club website: "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.
"Knowing that he was so highly-rated across Europe, Ronny was one of the first candidates we considered as manager.
"Having discussed the opportunity with him at length, we are convinced he has the talent and the determination to deliver very positive results for the club and our supporters."
The appointment comes after a hig profile search for a new manager, with Roy Keane at one stage appearing to be the favourite, as well as fellow former players Henrik Larrson and David Moyes, as well as Scots Owen Coyle and Paul Lambert.
