While things at Celtic appear to be increasingly on the up under the management of Ange Postecoglou, with the Bhoys currently on a run of six games without defeat in all competitions, there are nevertheless a number of positions in the 56-year-old's first-team squad that are lacking a considerable amount of depth.

Indeed, in a recent article for The Athletic, Kieran Devlin highlighted Celtic's need for an adequate replacement for Callum McGregor in the number six role, as, during the four-game period in which the central midfielder was sidelined back in September, the Hoops clearly lacked a player who could replicate the 28-year-old's "passing range, speed of thought and execution to accelerate attacks."

However, before Postecoglou enters the January transfer market in search of a backup for the Scotland international, perhaps it would be wise to take a closer look at one of the club's summer signings first - in the shape of Liam Shaw.

Indeed, after joining the club on a free transfer back in July, the 20-year-old said of his style: "I describe myself as a box-to-box midfielder, a lot of energy running up and down, I can score a goal, and be aggressive in that I like a tackle and I like to press people."

This is something that was evident in his 19 Championship appearances for Sheffield Wednesday last season, over which the £315k-rated man scored one goal and created two big chances for his teammates, as well as making an average of 0.3 key passes, 0.7 tackles and taking 0.5 shots per game.

While these statistics are not exactly mind-blowing, it must be remembered that his returns came while the midfielder was enjoying his breakthrough season in professional football within a side who were fighting at the wrong end of the Championship table - before ultimately suffering relegation.

Indeed, it is clear to see that the foundations are undoubtedly there for Shaw to blossom into a fine number six, something that will be developed further with more experience of first-team football.

However, with the 20-year-old being yet to make an appearance in the Scottish Premiership under the management of Postecoglou, it would appear a very wise move for the Bhoys boss to finally unleash the rarely-seen Shaw in the coming weeks and months, as the midfielder could prove to solve one of the 56-year-old's biggest issues at Parkhead.
