It is a gruelling month that lies in wait for Brendan Rodgers’ side with another five games to negotiate before they down tools in January and head for a sunshine break in Dubai.

They will relish the breather but on the evidence of the opening half of this season, there will be little need for any requirement to address seasonal affected disorder. Glasgow might be grey in December, but it has been nothing but blue skies overhead since Rodgers checked in.

All the signs are there that Rodgers will join the history books at Celtic Park as he pens the latest chapter at the club; on Tuesday he penned an interesting footnote into his era as he enjoyed the most successful start to his managerial regime than any other incumbent of the post.

The Celtic manager notched up his 19th domestic game unbeaten with Tuesday's win over Hamilton Accies, eclipsing the previous record held by Martin O’Neill in his inaugural season at the Parkhead club - 18 - as Celtic beat Hamilton Accies.

Interesting, then, that the goal on the night he set a new benchmark at the club should come from Leigh Griffiths, a player who has been overshadowed for much of Rodgers' term.

The striker and Moussa Dembele started only their third league game together this season, with the former teeing up Griffiths for what proved to be the only goal of the game just before the interval.

Accies would have gone into the game expecting to have to work out the best way to negate Celtic; their only issue in the early stages was that they had to work out how their hosts had actually set up.

With Dembele and Griffiths up front and Scott Brown dropping deep whenever Celtic were without the ball, it was a different set-up than normal from Brendan Rogers.

And yet, Accies were more resistant in the initial stages than Celtic might have expected.

It took until nine minutes before the break before the Parkhead side took the lead, with Dembele and Griffiths combining to break the deadlock.

While Rodgers has maintained for much of the season that his system doesn’t necessarily suit what is increasingly regarded as an old-fashioned front pairing, it was interesting to see the two strikers dovetail.

The Celtic manager bristled somewhat last weekend as he insisted that there “was nothing in his contract” that said he has to play Griffiths, but on home domestic fronts it is a decision that will always win applause from the hoops support.

Griffiths, who netted against Partick Thistle on Friday night, has been itching for his chance and Dembele has been off the boil - in comparison to the bar he set in the early stages of his Celtic career – since he returned from international duty last month.

If the young Frenchman was desperate to net from open play he didn’t show it with a pass that was startlingly unselfish.

As Tom Rogic sent a pass the entirely split the Hamilton Accies defence, Dembele beat the advancing Garry Woods with one step forward but instead of shooting, squared the ball to Griffiths. The striker seemed to hesitate initially before rolling the challenge from Grant Gillespie and slotting into the net.

Last season’s 40-goal scorer almost netted a second within a minute only to send his shot wide, but the signs were there that Celtic would add to their tally as Hamilton opened up; Patrick Roberts was unfortunate not to, while Dembele had one attempt knocked over at the back post as the game inched towards the break.

Mikael Lustig picked up where Celtic had left off after the break with one effort over the bar as he burst into the box and for much of the second period it was effectively one-way traffic.

Rogic showed some quick feet on the edge of the box only to find no-way through, while Dembele has one half chance saved by Woods.

Gary Mackay-Steven, on just before the hour mark for Callum McGregor, almost got the second goal that would have allowed Celtic to relax a little when he missed connecting at the post after the trickery of Roberts had teed him up.

Rogic was next to try his luck at he unleashed a ferocious effort from distance, only to see it fly just wide of the target. The Aussie has the ball in the net - a goal his play would have deserved - only for the effort to be rendered immaterial by the fact Allan Crawford's whistle had already gone for an infringement.

A 1-0 lead is always tenuous - no matter how far ahead you are in the table - and as the game drew to a close Accies almost claimed a leveller when Eamonn Brophy - he who celebrated with a backflip when he netted the 1 in that 8-1 game - when he was given time and space to advance before raking a shot just past Craig Gordon's left-hand post.

The scoreline lent an uneasy edge to the last few minutes of the game, a tension that Celtic have not been used to in recent months.

It counted for little as normal service delivered what has become to feel like an almost inevitable three points.
