With the transfer window slamming shut on Thursday night, it seems reasonable to assume Celtic supporters are on the whole underwhelmed by the club’s activity - or lack of it - in the January market.
Nicolas Kuhn has come in from Rapid Vienna and may well prove to be an astute capture, although a wide player wouldn’t have struck me as Celtic’s top priority this month.
Brendan Rodgers has spoken on more than one occasion of the need to add "quality" to the squad, so one can only suppose he too is less than impressed with the lack of incomings this month.
With a five-point advantage at the top of the Premiership and two wins already over Rangers this season, it is clearly not beyond the current squad to go on and win a third successive title, but the concern for Celtic fans will be that it is far from a foregone conclusion.
As in the season where their "10-in-a-row" hopes were scuppered, there is a sense that the reigning champions have allowed Rangers a sniff of a title when they should arguably have been out of sight, given the upheaval at Ibrox and the disparity in terms of the financial clout of both clubs.
Rodgers’ return was not universally acclaimed, and nor has the football played this season been. If no serious strengthening of the squad takes place over the next day or so, the board will take more flak from a fanbase that has already shown signs of discontent in recent weeks.
