Neil Lennon has been named as Celtic's new manager on a rolling 12-month contract.
He had been in charge on a temporary basis after Brendan Rodgers left for Leicester in February and guided the Hoops to an eighth successive Scottish Premiership title and victory against Hearts in last weekend's Scottish Cup final.
Lennon, who racked up 304 appearances as a Celtic player, says he's "delighted to once again be part of the one of the biggest clubs in the world".
The Northern Irishman collected five Scottish Premier League titles, four Scottish Cups and two League Cups during his spell as a player at Parkhead before landing three Scottish Premier League titles and two Scottish Cup wins as manager.
“It is a massive honour to be named Celtic manager once again. I had always dreamed of returning to this role on a permanent basis and I am absolutely delighted to once again be part of one of the biggest and best clubs in the world - an institution which really does mean so much to me and one which has always been such a huge part of my life," said Lennon of his appointment.
“When I was asked to take over in February, I felt it was my duty to do so. Celtic will always be my club and I wanted to help finish the job which had been started.
“I was delighted with the way the players stuck to their task and delivered another historic success, which is unlikely to ever be repeated. I was also delighted to receive such great support from our fans since returning, something for which I will be forever grateful.
“In the space of just a few weeks, Trophy Day at Celtic Park and securing the Treble Treble at Hampden are two of my greatest days in football. The energy, total commitment and passion from our supporters, the effort, the talent and desire from our players. It’s these qualities which make our club great and deliver such historic occasions.
“I want to be part of delivering more of these great days and great achievements and I look forward to working with the players, the staff and the fans to make this happen.”
John Kennedy continues as assistant manager, with former Republic of Ireland winger Damien Duff also staying in his role as first-team coach.
