Montgomery joins from A-League side Central Coast Mariners, putting pen-to-paper on a three-year deal.

The 41-year-old arrives at Easter Road with a reputation as one of the best young coaches in Australia after leading the Central Coast Mariners to the A-League Championship last season; their first in 10 years.

As a coach, Montgomery started in the Central Coast Mariners Academy and revitalised their youth system, alongside Raimundo, implementing a new game model and structure. Within two years, the Mariners Academy was known as one of the best in Asia - and number 17 in the world - for developing young players for the First Team.

In 2021 he became the Club’s Head Coach and turned them from a side competing in the lower echelons of the division to reaching the A-League Finals. He also helped the Mariners reach the Australia Cup Final for the first time in the Club’s history.

An exciting coach, Montgomery’s sides have a strong reputation of working hard, attacking football and developing young talent.

He also made over 500 appearances as a player, featuring in the English Premier League and English Championship, alongside the Australian A-League, and earned two caps for Scotland’s Under-21s.
