Ange Postecoglou has nailed his Celtic colours to the mast ahead of this weekend's derby fixture against Rangers.

Brendan Rodgers' side - the Premiership league leaders - will make the short journey across Glasgow to face their arch-rivals on Sunday lunchtime.

The champions hold a slender lead at the summit of just one point having played a game more than the Ibrox club.

Postecoglou, who left Celtic for Tottenham last summer, very much had Rangers' number during his time in charge of the Hoops, winning back-to-back titles, and five out of the six domestic trophies available to him in Scotland.

And he's looking forward to watching the game this weekend before taking charge of Spurs' latest home match against Nottingham Forest at 6pm on Sunday evening.

"Yeah, I think it's early on Sunday so I'll definitely be watching," the Australian said. "It's one of the biggest rivalries in world football, mate.

"I'm very much on the green and white side, and yeah, I'm hoping the lads... I know what it means to the supporters win that game.

"As much as we talk about derbies and they mean more - this one does. I lived and breathed it for a couple of years and it's a really important game for both clubs. 

"Looking at the table, this year, I think it takes on extra significance because you know most of the time that's what's going to separate the sides at the end of the year. So, it'll be a cracking game and I'll be tuning in."

Spurs are in the hunt for Champions League football next season and sit just two points behind Aston Villa who currently occupy fourth spot. 

Postecoglou has received many plaudits for the style of football he's implemented in North London, and he's made no secret of his ambitions to challenge the likes of Manchester City, Liverpool and Arsenal for the title next term.
