Celtic boss Brendan Rodgers will be aware that his side are short in several areas due to his five-man list of absentees currently on international duty at the AFC Asian Cup.
Reo Hatate and Daizen Maeda have both played their part for Japan at the tournament, and the Samurai Blue will take on Bahrain later today to try and seal a place in the last eight.
In the case of Hyeongyu Oh and Yang Hyun-jun, they are already safely through to the quarter-final after seeing off Saudi Arabia in a dramatic penalty shoot-out victory.
Despite neither player featuring in the triumph, both will now stay in Qatar for a while longer rather than return to Celtic.
This may come as a slight frustration to Brendan Rodgers amid a lack of options in the final third heading into a congested run of fixtures.
At centre-forward, Kyogo Furuhashi is currently the sole senior option for the Bhoys. Nevertheless, he could soon be joined by Norwich City striker Adam Idah, who is reportedly close to sealing a loan move to Parkhead.
Marco Tilio is Australia’s only representative from the Scottish Premiership champions and will also be part of their contingent for the next phase after the Socceroos saw off Indonesia 4-0 in the last 16.

Three Celtic players set to meet in AFC Asian Cup quarter-final
In a swift turnaround, South Korea will take on Australia on Friday at Al Janoub Stadium, where Oh, Yang, and Tilio could meet on the international stage [Sydney Morning Herald].
Kick-off is at 3.30 pm GMT as two of the favourites for the tournament go head to head for a place in the semi-final.
It should be noted that Celtic fans in the United Kingdom will only be able to watch proceedings on TrillerTV+, which will involve signing up for a £7.99 monthly subscription.
Nevertheless, an option for a seven-day free trial is also advertised on their website. For those elsewhere, LiveSoccerTV has a full list of available broadcasts worldwide.
The hunt for AFC Asian Cup silverware is beginning to intensify, and there is a possibility that the Hoops could have some representation in the final, which takes place on February 10th.
