Ange Postecoglou has insisted he "couldn't be happier" after Celtic lifted the Scottish Premiership title.
The former Celtic manager admitted he was thrilled to watch his previous club win the league with a thumping victory over Kilmarnock.
Brendan Rodgers' side clinched the league crown at Rugby Park before returning to Celtic Park for celebrations with supporters.
Postecoglou - now Tottenham boss - revealed he had watched the match as he reflected on the his time at the "unbelievable club".
In his press conference, the former Parkhead boss commented: "I love them, mate. Yeah, brilliant.
"Great people, great manager, great staff, great footballers, unbelievable club.
"I watched the game and I know, because I have experienced it, how they would have felt at that final whistle and then going back to Celtic Park late at night.
"It's a pretty special place and credit to them, it was a difficult year for Brendan and the guys but when it mattered, when it counted they stood up and I couldn't be happier for everyone there."
Meanwhile, Postecoglou described Spurs' match against Manchester City as the worst experience in his career.
Tottenham lost 2-0 to the Premier League leaders in a match where supporters were conflicted given a positive result against Pep Guardiola’s team would have put rivals Arsenal in pole position to win a first Premier League title in 20 years.
Postecoglou threw out any suggestion his team wouldn't go for the win and has now reflected on the nightmare scenario as he demanded his integrity is never quesitoned.
“Look, I will try and explain it in this way. That is probably the worst experience I have had as a football manager in a game,” Postecoglou admitted.
“Because once I realised I got it wrong, in terms of what the atmosphere would be like and what people felt, I got a real anxiety within me of what happens if Man City, best team in the world and disposing of teams quite easily in the build-up, what if we play as well as we can, but they beat us 5-0?
“I got in cold sweats thinking about people questioning my integrity and the people I work with."
