Ange Postecoglou has been named new manager of Tottenham.

The Australian has signed a four-year deal with Spurs, leaving Celtic after leading them to a domestic Treble.

"We are excited to have Ange join us," said Tottenham chairman Daniel Levy.

"Ange brings a positive mentality and a fast, attacking style of play. He has a strong track record of developing players and an understanding of the importance of the link from the academy - everything that is important to our club," he added.

Postecoglou, 57, is one of only five managers - along with Jock Stein, Martin O'Neill, Brendan Rodgers and Neil Lennon - to secure a domestic clean sweep with Celtic.

"It has been a pleasure working with Ange, a great football manager and a good man. He has served the club with such energy and determination and delivered a phenomenal level of success," Celtic chief executive Michael Nicholson said.

"Of course, we wanted Ange to stay at Celtic and while there is real disappointment we are losing him, he has decided he wants to look at a new challenge, which we respect."
