How big is Kyogo Furuhashi loss? And how do Celtic replace him?

It is inconceivable that Celtic will not move for another striker in the remaining week or so of this transfer window.

There are other options in the building - but not a like-for-like replacement.

Adam Idah was the big-money signing of the summer and, while the Republic of Ireland striker has contributed eight goals and forced the winner against Young Boys on Wednesday, he has failed to find the net himself in 14 games.

He has pace and power and, while at 23 years old he has time to come good, he does not possess Kyogo's movement or deadly finishing ability.

Regular left winger Daizen Maeda is often utilised through the middle at international level with Japan and the expected return of Portuguese winger Jota may mean Maeda moves into that central role.

However, his work in the channels – taking on full-backs and turning defences with his pace while hassling them when out of possession – is so invaluable to the way Celtic play that deploying Maeda centrally may be solving one problem by creating another.

Johnny Kenny has been brought into the first-team fold after a prolific goalscoring spell on loan at Shamrock Rovers but is still to prove himself at the top level.

With a domestic Treble to play for and a first appearance in the Champions League knockout stages since 2013 still to come this season, Celtic will surely look to beef up their attacking options this January window.
