Celtic will round off their season with the Scottish Cup final against Inverness on Saturday and can complete the domestic treble with a victory.
The Hoops have enjoyed an excellent campaign under Ange Postecoglou, as they have already wrapped up the Scottish Premiership and League Cup trophies, and they may now have one eye on 23/24.
Whilst the head coach could improve his squad by dipping into the transfer market to add fresh faces to the group, the Australian boss could delve into the academy to add competition for places.
One young gem who could be ready to make the step up to playing regular football for Celtic is youngster Adam Montgomery following his impressive loan spell with St Johnstone.
He is a 20-year-old defender who can play as a left-back or as a left-midfielder and the dynamo could be the long-term heir to Greg Taylor's position in the side.
How did Adam Montgomery perform this season?
Montgomery had already played 20 first-team games for the Hoops prior to going out on loan this season and racked up one goal and four assists in 33 appearances in all competitions for the Saints.
He showcased his defensive ability alongside his attacking prowess as the battler made 2.2 tackles and interceptions per game and won 53% of his physical duels.
Taylor, meanwhile, made featured in 31 Premiership games for Celtic and won 51% of his contests and made 2.2 tackles and interceptions per outing. The Scotland international also assisted four goals from left-back, which shows that both players are attack-minded defenders who can also put their foot in to win possession back for their sides.
Montgomery's performances in the Scottish top-flight suggest that the youngster, who is five years younger than Taylor, could be the long-term heir to the current Hoops star's position in the team, based on their similar attacking and defensive outputs.
The talented youngster was rewarded for his efforts by being named on the shortlist for the Scottish Football Writers' Young Player of the Year, which was ultimately won by Motherwell's Max Johnston.
St Johnstone boss Steven MacLean hailed the gem as "outstanding" and his former manager Callum Davidson claimed that the ace has a "big future" ahead of him, which shows that the defender impressed both of his coaches during his loan spell.
The 20-year-old still has plenty of time left ahead of him to develop and grow and being the back-up to Taylor for another season could provide the seasoned Hoops defender with competition and allow Montgomery to learn from him before eventually taking over the starting berth in the future.
