- Kyziridis & Shankland secure Hearts win and send them eight ahead at the top
- Celtic's McGregor equalized early Murray own goal
- Hearts go 13 games without defeat for the first occasion in 27 years
The dominant Edinburgh side surged eight ahead of their Glasgow rivals at the summit of the Scottish top flight to strengthen their early title credentials and deepen the malaise around Brendan Rodgers' side.
Alexandros Kyziridis' fine strike and Lawrence Shankland's penalty gave Derek McInnes' side a two-goal advantage that the reigning champions could not recover from.
The young defender - one of three youngsters in the Celtic XI - slashed into his own net in the early stages to put Hearts ahead at a bouncing Tynecastle, and it was the 22-year-old's foul that led to the penalty.
Callum McGregor's classy first goal of the season had quickly cancelled out the first goal, and the Swedish attacker almost put Celtic in front, choosing placement over power and allowing the Hearts keeper to make a crucial stop.
But Derek McInnes' irrepressible Hearts regained dominance to hand Celtic to successive league defeats for the first time since last year.
It also gives the Edinburgh side a significant lead at the summit.
The last time they were this far ahead was in the 2005-2006 season under George Burley, when they ultimately finished second - a rare instance that a team has not secured the title having held such a lead in the past 27 years.
The Hearts coach, whose Aberdeen side were runners-up to the champions on multiple times, has been working hard to downplay championship discussions, as Hearts seek their maiden league title since 1960.
The Celtic boss has seen it all before at the club - both flawless and stuttering starts to a season. He's yet to finish second best.
But on the weekend's performance, this Hearts team showed they need to be taken seriously.
Match Analysis: Hearts Take Advantage of Depleted The Visitors
Hearts started with the confidence of a side unbeaten in the league this season - the popular attacker poked a cross in for Shankland to fire off target.
Celtic didn't help themselves with some uncharacteristic carelessness in possession and they buckled under their initial test.
Claudio Braga's header was tipped onto the woodwork by the Celtic keeper and Shankland's return ball was diverted goalwards by the unfortunate Murray, in for the absent center-back.
The away side grew into the contest and started stringing passes together. From a flowing attack, the midfielder released the full-back to set up the captain, who slotted home.
Apart from the opportunity for Nygren, Celtic found it hard to generate chances for lone frontman Jonny Kenny or his replacement Shin Yamada amid the unavailability of injured forwards their key strikers.
The home team rediscovered their energy and versatility in attacking from across the final third. The Greek forward, one of the finds of the club's relationship with shareholder Tony Bloom's Jamestown Analytics, fired a low shot past Schmeichel from the edge of the box.
Immediately after, the defender tripped the midfielder in the inside right channel and Shankland scored. And it could've been an even more handsome win, had replacement Ageu not been denied by the shot-stopper.
The visitors' performance after the break was partially encapsulated in two incidents involving record signing Arne Engles.
The midfielder's wayward free-kick delivery was in stark contrast to his European display in the Europa League win over Sturm Graz and the national team player was then booked for a professional foul.
What They Said
The Hearts manager: "You see how hard the players work, the togetherness. That's not sufficient on its own to win games consistently.
"Our strength lies in, is good technical ability. You're seeing that from a lot of players who have been here previously. Some of the new signings are eager to show that.
"We've got a good thing going at the minute, but it's only three points. It's important for us to keep winning. We've got much work ahead, plenty to improve. After the first two rounds is normally an indication of your standing."
Celtic manager Brendan Rodgers: "It's a really poor goal from our perspective. We failed to push up when the play was recycled as a defensive unit so when they play it, they should have players offside but didn't. We have got to do better with the shot.
"Plenty of matches to play for. It's only the beginning. It's only nine games in. Clearly, being eight adrift is not what we would want. The positive is there's numerous fixtures to play.
"We now have to focus on the here and now and look to achieve greater stability and more quality in our play."
What's Next for Both Sides?
The Glasgow club are returning to their stadium on Wednesday against promoted side Falkirk (19:45 GMT). At the same time in the Scottish Premiership, Hearts are at St Mirren.
