They just can't be beaten.
Make that 68 domestic games unbeaten for Celtic. Brendan Rodgers' Hoops maintained their impressive streak with a 2-2 draw against Hibernian on Sunday - but they have Mikael Lustig to thank.
After going 2-0 behind to a Scott Sinclair double, Neil Lennon's men fought back admirably to earn a point at Easter Road, but they came agonisingly close to becoming the first side to beat Celtic in a domestic game since May 2016.
With the scoreline at 2-2 in the 93rd-minute, Hibs thought they had stolen it right at the death when Craig Gordon made a hash of trying to clear a cross. It fell to Oli Shaw and, with Easter Road ready to erupt, Lustig got back to make a crucial intervention and salvage a point for Celtic.
Two dropped points means the Hoops' lead at the top of the Scottish Premiership is now just five over Aberdeen and Rangers.

Although Celtic avoided defeat, their performance was less than convincing, with Rodgers' players - particularly the defence - coming in for some stinging criticism after the final whistle. Lustig was the hero at the end but it didn't stop disgruntled Celtic supporters from singling him out too.
