Jack Ross and his unbeaten Hibs side have a massive - and rare - opportunity when they head to Ibrox for Sunday’s mouthwatering showdown in Govan.

The chance for a non-Old Firm side to sit at the Scottish Premiership summit in October is not something that comes around too often.

Not many will give them much hope of being in this position come May and the same goes for city rivals Hearts who could also end the weekend on top spot if Hibs earn a point and the Jambos are victorious against Motherwell.

Even the Steelmen themselves could be looking down on the rest if they beat the men in maroon and Rangers and Hibs draw.

It makes for an exciting weekend but the Hibees know if they can claim victory against the champions in their own backyard then that would send them top.

And it would certainly make things a little interesting but those outside of the Glasgow giants who have enjoyed such a lofty position in October previously have shown to be scared of heights and fallen away.

Here, Record Sport Online picks out five previous examples where they have been top but unable to hang on and become the side to break the Old Firm’s 36-year title stranglehold.

Hearts 2018/19

Craig Levein’s men went 13 games unbeaten in all competitions until they suffered defeat at the hands of a ruthless Rangers at Ibrox.

It was a big chance missed to really turn up the heat on the Light Blues in Steven Gerrard’s first season in charge.

Ryan Kent, Alfredo Morelos and Scott Arfield were all on target in a 3-1 win with Michael Smith’s sending off in the second half giving the Jambos, who pulled one back through Jimmy Dunne, a mountain to climb.

Despite that defeat, Hearts remained top with city rivals Hibs second after the Old Firm started slowly.

But Levein’s men hit the skids with a scoreless Halloween derby draw the first of a seven-match winless run - including four defeats - and they eventually finished sixth.

Aberdeen 2015/16

The Reds made a flying start to the season with a record-breaking eight consecutive league wins on the spin.

But they were brought crashing back down to earth after that when they failed to win any of their next five in a run that saw them lose four - including a 5-1 thumping by St Johnstone.

The final match in that sequence was a 3-1 defeat at Parkhead on Halloween which ended any notion of a proper title challenge and they finished 15 points behind Ronny Deila’s side.

Hibs 2012/13

Pat Fenlon’s time in charge at Easter Road isn’t remembered too fondly so it’s hard to believe they were sitting at the top of the league in October.

However, that was only for 24 hours after goals from Eoin Doyle, Leigh Griffiths and David Wotherspoon put basement side Dundee to the sword.

Celtic went back to the summit the following day when Georgios Samaras scored the only goal and Hibs eventually finished in the bottom six - 28 points behind the Hoops!

Hearts 2005/06

This is the biggest ‘what if…?’ of all those teams who were top in October in the last 25 years with George Burley sacked with Hearts flying high.

Burley was bulleted by trigger-happy Vladimir Romanov on the morning of a 2-0 win over Dunfermline at Tynecastle after the former Ipswich boss had led them to eight consecutive wins and two draws.

Defeat in the Edinburgh derby at the end of October was their first loss but even after the appointment of Graham Rix they stayed in contention but a Ne’erday defeat to Celtic saw the momentum swing towards the Hoops.

They eventually finished 17 points behind Celtic but still pipped Rangers to second spot to secure Champions League football.

Hearts 1997/98

Jim Jefferies as Hearts manager

The Jambos threatened to gatecrash one of the biggest ever battles between the Old Firm as Rangers were going for 10-in-a-row.

Jim Jefferies assembled an impressive squad at Tynecastle and they made a solid start to the Scottish Premiership season.

An impressive 4-1 win at Fir Park on October 4, 1997 made it five wins on the trot with four of those on the road.

Colin Cameron, Stephen Adam, Neil McCann and Jim Hamilton blew the Steelmen away in a first half blitz but defeat the following week at home to eventual champions dented their title hopes.

The Jambos still ran the Old Firm close that season and were only five points behind Rangers in second and seven adrift of the Hoops who were crowned champions.
