Callum McGregor has issued an emotional departure message to Ange Postecoglou after it was confirmed that he would be heading to the Premier League with Spurs.
The 57-year-old Australian, who won the domestic treble with Celtic this season, moves south to London to replace Antonio Conte.
Conte was sacked in late March, with Cristian Stellini and then Ryan Mason taking temporary charge. Postecoglou will officially join Spurs on July 1.
After it was confirmed his manager would be leaving, Celtic captain McGregor said: “It has been great to work with the gaffer over the past two seasons and to achieve the success that we have, especially achieving yet another treble at the weekend.
“In fact, to win five out of six domestic trophies is a tremendous achievement and that is testament to the real focus and relentlessness of the manager, the players and our whole backroom team who have all worked so hard.
“I thank all our supporters again for what they have given us this year. The scenes at Hampden and Celtic Park, when we celebrated our success together will stay with me forever.
“We have delivered something very special to our fans and done it, under the manager’s direction by playing an exciting and attractive brand of football. As all the players do, I wish Ange great success in his next challenge.
“We move on ourselves to our own challenges too. Our performances this season mean we will take our place deservedly in the Champions League and we can’t wait for it.
"It will be brilliant to have these great nights back at Celtic Park and I am sure our fans are looking forward to experiencing this again, as well as watching us striving to defend all our domestic titles.
“The players will enjoy a well-earned break and when we return we will get right behind the new manager, we will be united and, as ever, will do all we can to bring our fans continued success.”
Tottenham chairman Daniel Levy said on the club’s website: “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.
“We are excited to have Ange join us as we prepare for the season ahead.”
Tottenham added Postecoglou’s backroom coaching staff would be confirmed “in due course”.
Postecoglou won five major trophies in his two seasons in charge of Celtic after replacing Neil Lennon in June 2021.
