With a 1-1 draw against Kilmarnock on Saturday, Celtic equalled a 100-year record. By avoiding defeat to a stubborn Killie, Brendan Rodgers' Hoops made it 62 domestic games unbeaten, equalling the British record set by Willie Maley's Celtic back in 1917.
However, it won't be a game, or indeed a performance, that Rodgers will rank too high among the 62. Just like against Celtic's Old Firm rivals Rangers, Steve Clarke's side travelled to Glasgow and came away with a hard-earned point.
The Rugby Park men set up to frustrate the Scottish champions but, when Leigh Griffiths opened the scoring after 43 minutes, it looked as though it was going to be business as usual for the home side.
Kilmarnock came out fighting after the interval, though; Jordan Jones grabbing an equaliser on the hour mark. After that, the away side were able to hold firm and claim a valuable point which kept them above Dundee at the foot of the table. The result meant Celtic are just one point ahead of Aberdeen now after they beat Ross County 2-1.
Celtic's upcoming schedule is rather daunting. They host Bayern Munich on Tuesday night before two Premiership trips to St Johnstone and Ross County either side of an international break. Then they have an unenviable task ahead of them as they take on Paris Saint-Germain at the Parc des Princes.
After that, there is a triple-header of clashes with Motherwell, including the League Cup final. It means that Celtic don't have a Premiership game at home again until December 2, but perhaps that's not a bad thing as Celtic are finding it easier to pick up wins on the road this season than on their own patch.
Killie Learn From Their Mistakes
The first half followed an unsurprising pattern. Celtic dominated possession and created chances to score, but Clarke would have been furious with how his men allowed the hosts to clinch the opener just before the break.
Rodgers started 19-year-old midfielder Eboue Kouassi and he was the creator for Griffiths' strike. After winning the ball in midfield, the Ivorian was allowed to surge into space completely unchallenged and unchecked.
Even after doing so, he was afforded the time and space to look up, spot Griffiths' run and clip a ball over the defence from which the striker slotted coolly through the legs of keeper Jamie MacDonald.
It was hugely disappointing from an otherwise impressively organised Killie side. Clarke would have let them know that in no uncertain terms in the dressing room a few minutes later.
After the break, Kilmarnock showed a renewed sense of adventure as Jones, not unlike Kouassi, surged through the Celtic midfield before cracking the inside of the post with a 20-yard drive. However, Jones' was quick to react, gathered the ball, played a one-two with Rory McKenzie and fired the equaliser past Craig Gordon.
From that point, Kilmarnock became extremely compact and difficult to break down. As you can see below, Killie got plenty of men behind the ball and maintained a pretty good shape. They cut off supply to Scott Sinclair and Griffiths in the box, forcing Kristoffer Ajer to have a pop from distance.
But there was to be no winner for the champions, unlike in September last year when they battered Kilmarnock 6-1 here.
Far From Home Comforts For Celtic
It was frustrating for Celtic who, despite making six changes with Rodgers wary of overworking his players before the visit of Bayern this week, looked laboured and a bit heavy in the legs. The league leaders do have a heavier fixture schedule than most, with Champions League clashes and League Cup exploits to contend with alongside their league commitments.
Although Rodgers has the best resources in Scotland, fixture congestion is testing and stretching his squad and, much to his chagrin, rotation failed to produce three points on Saturday.
Of course, it's not the first time Celtic have struggled to break down a stubborn opponent's deep defensive line at home this season.
Back in August, Callum McGregor came off the bench to score a late equaliser to avoid defeat to St Johnstone, while the Scotland international was once again the saviour in September when he struck twice to stop Neil Lennon's Hibernian walking away from Celtic Park with all three points.
It's been a recurring theme at Celtic Park so far this season. Rodgers' side are always going to dominate possession on their own turf. Against Kilmarnock, they had 64 per cent, while they had 59 per cent when facing Hibs and 66 per cent versus St Johnstone. They are averaging just under two-thirds of possession in those games, but are finding it tough to break down a compact and organised defence.
Of course, they have had some success at home. They beat Ross County 4-0 and hammered Hearts 4-1 on the opening day of the season. However, they needed a 61st-minute goal from Olivier Ntcham to beat struggling Dundee and the difficulty with which Celtic have broken down these teams will certainly have factored into Rodgers' mind.
Celtic are the best team in Scotland, so clubs are not going to come to Celtic Park with a particularly enterprising game plan. In fact, frustrating afternoons like against Kilmarnock are likely to be a regular fixture of Celtic's season. Future opponents can study videos of how Clarke set his team up to stifle Celtic's threat and emulate his example in the hopes of earning a point – or perhaps more – when they travel to Glasgow.
Last season, only two teams managed to stop Celtic winning in front of their own supporters: Rangers and Partick Thistle. However, it was still interesting to note that they scored 59 goals away from home, 12 more than at Celtic Park.
This season has had a familiar ring to it but, with Aberdeen looking like they are ready to mount a serious title challenge, dropping points at home may cost Celtic in the long run.
