Ronny Deila will leave Celtic, it has been announced, days after defeat to Rangers.
Ronny Deila will leave Celtic at the end of the season, the club have confirmed via their official website.
Deila said: "It is vital that the Club comes first and instead of me being the focus, hopefully now the team and the Club can be the focus as we enter this final important period of the season.
"It was an absolute privilege to be named manager of Celtic, such a wonderful football club, and I have enjoyed my time here immensely. I will never forget the welcome I received almost two years ago at Celtic Park from so many fans. When I joined Celtic I knew I was coming to one of the world's great football clubs.
"There have been some great times and I am delighted that we have brought some trophies to the club.
"I was delighted in my first year to bring our fans a League and Cup double and enjoy some European nights at Celtic Park, and I am pleased this season to be well in contention to win another Premiership title.
"There have been some disappointments and times when we have not achieved what we had hoped for and I'm realistic and honest enough to admit that, but I know that the players, myself and my backroom team have always given everything we had to bring success to our supporters.
"I would like to thank everyone who has supported me so well at the club. The fans have been magnificent during the past two years. Our fans are the heartbeat of the club, they have always given myself and the team such amazing support and always created such a great atmosphere. We have always given our best for them and I will always be a Celtic supporter too.
“I also want to thank Dermot Desmond, Ian Bankier, Peter Lawwell, the players and my staff. They have given me everything.
"My total focus now is on retaining our Premiership title and making it five-in-a-row for our great club and proving that we are the best in the country. Myself and the players will be giving everything we can to achieve this and I know that starting on Sunday we must all unite and drive the club on and really go for what we all want as Celtic supporters - to be Scottish Champions once again."
It is just days since Deila's Celtic were defeated by Rangers in the Scottish Cup semi-final, losing on penalties at Hampden Park.
Celtic are on course to win a second league title under Deila, but these titles have been achieved with little challenge from rivals clubs, with Rangers working their way back to the top flight.
Now with Rangers securing promotion, all parties appear to have amicably parted ways, believing a fresh approach is needed.
Deila was a surprise appointment in the first place, and his failure to qualify for the Champions League in successive seasons has been the biggest black mark over his record, even unable to get out of the Europa League group stages this season.
He has managed Celtic over 118 matches with a win percentage of 63 per cent.
