Former Barnet boss Harry Kewell is delighted joining the backroom staff at Celtic.
Celtic boss Ange Postecoglou has appointed former Leeds star Kewell as a first team coach.
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."
