Leigh Griffiths needs to take his chances in the Celtic starting line-up.
For Leigh Griffiths it is reaching make or break time in his Celtic career.
After signing for the club at the start of the calendar year from Wolverhampton Wanderers, Griffiths has endured a frustrating time at Parkhead after slipping down the selection order.
The Scottish striker was brought in to lead the line after showing some excellent form in League One, but he has failed to make the impact expected since signing up.
Despite being a clinical finisher, his goalscoring talents haven't been on display with the Bhoys and he has been a peripheral figure.
This season, Griffiths has played 18 times but most of these appearances have come from the substitutes' bench.
During this time he has scored four goals, but dislodging Anthony Stokes and John Guidetti for a starting place up-front has proved too tough for the 24-year-old.
However, with Guidetti struggling for form, having not found the back of the net in any of the club's previous four matches, Griffiths is set to be handed his chance.
Manager Ronny Deila has overlooked Griffiths for much of his time at the helm at Parkhead so far, but the Norwegian has hinted that the he will be given his chance over the Christmas period and it could be a case of now or never for the former Hibernian man.
With the January transfer window coming up, Griffiths's future at the club remains uncertain, but he has the chance to prove his worth in the coming weeks.
Celtic have not been at their impenetrable best this season, having lost three times already, and they need someone to take the goalscoring responsibility off Guidetti.
The Swedish striker's form recently may have dipped, but he remains a talent and Griffiths will have to ensure he hits the ground running after being brought into the team if he is to keep his place in the line-up.
If Griffiths is unable to, it may spell time on his career at Celtic and he will know that the pressure is on Boxing Day, when he is expected to be handed a starting berth against Ross County.
