Celtic boss Ange Postecoglou has appointed Harry Kewell as a first team coach at Parkhead.
The 43-year-old has been out of work since being sacked by Barnet last year.
Kewell has been stuck in the English lower leagues, having varying levels of success with Crawley Town, Notts County, Oldham Athletic.
His appointment sees Stephen McManus move from the first-team to work with Celtic's B team in the Lowland League.
Kewell said: “It is a massive honour to join Celtic and team up with Ange.
"He and his backroom team and the players have done brilliantly in their first year together, producing winning football in a great style.
"To turn things around and become Champions so quickly is a huge testament to Ange and everyone else at the club.
“The manager is synonymous with attacking, exciting football, something he delivered on last season and something I know Celtic fans have loved right across the generations.
"We will be aiming to give our fans more of the same going forward and I look forward to playing my part in bringing this to our supporters. "
Postecoglou is delighted to have Kewell and outlined the process behind the reshuffle which has moved McManus.
He said: “I am really pleased that Harry has agreed to join my staff. He knows the game inside out at the highest level and wants to play football the way myself and my team see it.
“I know he is hugely excited about joining Celtic, he is well aware of the scale of the club, what our ambitions are and I know he will make a really positive difference to my team.
“I was keen to restructure our coaching set up, a critical part of this was having a close link between the first team and B Team coaching structures.
“Stephen’s role will also be hugely important for us as we look to get that conveyor belt of talent going between the B Team, directly up to the first team.
“The B Team will again compete in the Lowland League, something which will be a crucial development opportunity for our young players as they aim to progress and advance further.
“I wanted a really strong connection to the development of our B Team and Stephen, with his knowledge of our current first-team philosophy and demands will be ideal in this role.”
