No prizes for guessing this one.
Our pick for game of the weekend could not be anywhere else as the Premiership’s top two face off at Tynecastle with a five-point gap wedged between them.
Chat of a title challenge from Hearts is becoming more serious by the week, while Celtic appear to be on the verge of a crisis.
Defeat for Brendan Rodgers’ men, who beat Sturm Graz on Thursday, would stretch open a scarcely-believable eight-point advantage for Derek McInnes’ side.
The reigning champions are nowhere near their best, looking blunt in front of goal domestically amid continued protests aimed at the club’s board from a disgruntled support.
The leaders have had a full week to prepare, while Celtic had to get a sweat on in midweek, so the visitors can surely expect an intense approach from the home side.
Rodgers last tasted defeat against Hearts in March 2024, which was a second straight loss to the Edinburgh club.
Since then, Celtic have swept aside their weekend opponents in their past four meetings with an aggregate score of 12-1.
Remember the clocks go back in the early hours of Sunday… you will not want to miss this.
