Celtic have not found the back of the net with any regularity this season.
Celtic's goalscoring average so far this season is their second lowest in the past decade.
The Bhoys have scored just 1.89 goals per game on average this season, which represents a huge fall from the figures they were posting during the previous campaign.
Last season Celtic cruised to the Scottish title, scoring an average of 2.68 goals per game, and their lack of goals this time around has to be a major concern.
Ronny Deila was brought to the Bhoys with the hope that he would deliver a swashbuckling style to Parkhead, but the team appear to be struggling to adapt to his methods.
At the moment Celtic are four points behind league leaders Aberdeen and, although they still have games in hand on their nearest rivals, it is not a certainty they will come out on top.
Anthony Stokes is the current top scorer in the Celtic squad, but his tally of seven goals is not particularly remarkable.
Last season Kris Commons, who has barely featured this campaign, netted 32 times and it seems that nobody in Deila's squad will reach those figures this time around.
It is a source of worry and unless Deila can start to increase their attacking threat soon the pressure will continue to rise on his job.
