Celtic boss Ange Postecoglou has enjoyed a rather impressive hit rate with regard to recruitment during his Parkhead tenure thus far, with the 57-year-old having typically proven an astute operator in the transfer market.

Despite that near-on "perfect" record in terms of incomings, as per pundit Alan Hutton, one addition that has failed to work out is the signing of Danish midfielder, Oliver Abildgaard, with the 26-year-old having become something of a forgotten figure in Glasgow of late.

Having signed on a season-long loan deal from Russian outfit Rubin Kazan on deadline day during the summer, the towering asset has since gone on to play a peripheral role for the Scottish champions thus far, having featured just nine times in all competitions this season - totalling just 156 minutes.

That lack of action has seen the one-cap international fail to start a single games across all fronts this term, with even the injury absence of captain Callum McGregor prior to the World Cup break having not led to a more prominent role in the side at the base of the midfield.

According to pundit Frank McAvennie, something is simply "not right" regarding the 6 foot 4 dud's situation with the Hoops, with that coming amid reports that Postecoglou and co will look to terminate his temporary deal this month.

The Scottish Premiership outfit appear to have identified an ideal replacement who can help hasten Abildgaard's departure from the club, following speculation that the Bhoys are interested in signing Korean midfielder, Kwon Hyeok-kyu.

According to reports in his homeland - via journalist Barry Anderson - Celtic are believed to have "made an offer" to sign the 6 foot 3 colossus from K-League side Busan IPark, with the 21-year-old named as one of his nation's "bright prospects".

The towering youngster would clearly be able to mirror the physical attributes of Abildgaard as a result of his height, while also offering the benefits of his "high-tempo play, technique and physique", in the words of Anderson.

The South Korea U23 international illustrated his defensive prowess in the recent K-League campaign after averaging 1.6 interceptions and 1.0 tackles per game, with those numbers a superior record to that of Abildgaard who has averaged just 0.2 and 0.5 for the same two metrics, respectively.

With the latter man something of a spare part under Postecoglou at present, it could well make sense to replace the Dane with an up-and-coming asset such as Kwon, whom the title-winning coach can help to nurture and develop.
