It was almost impossible for Celtic to top their 2016/17 campaign. The Bhoys clinched a domestic treble and went unbeaten throughout the entire domestic season.
Such a feat will not be repeated this term after the shock 4-0 thrashing inflicted by Hearts, however, Brendan Rodgers' side have made strides in Europe this season.
They've been drawn against Zenit, not an easy side to overcome, in the round of 32 but should be confident of making it through to the latter stages.
But in order to do so, Celtic should spend in the January transfer market. RB Leipzig defender Marvin Compper is already on his way but the signings shouldn't stop there.
And in order to get a handle on what Celtic fans are thinking ahead of the transfer window opening on January 1, we canvassed the opinion of Bhoys fan John from Celtic Songs.
What is your number one fear for January?
My number one fear for January is not strengthening our back line for the challenge of the Europa League. Building from the back and creating chances up both wings as well as through the middle opens up our attack.
Right now I am not always 100 per cent confident when some of our defenders have the ball at their feet in a one on one situation
Which areas do Celtic need to strengthen in January and why?
Celtic need to strengthen the back line and in particular a strong centre-back who is not injury prone. Someone younger, tall, strong, and fast.
I would also strongly consider another forward as we are likely to lose Moussa Dembele sound and although I like Odsonne Edouard so far he is not 100% proved himself.
What would your dream January transfer window look like?
My dream transfer window would be anything keeping the Europa League in mind and building towards a much better run in the CL next season. Spending money and sign the players needed with both of those in mind.
