Former midfielder Andy Halliday does not "see an area of weakness" in a Hearts side he feels are "the real deal".
The Jambos are now firmly in the driving seat to win a historic Scottish Premiership title after their 1-0 victory against Aberdeen was followed by an Old Firm draw.
Derek McInnes' side have responded impressively to a defeat at Ibrox two weeks ago by securing back-to-back home wins.
The Gorgie club now have clear daylight at the summit, six clear of Rangers and eight ahead of Celtic, who have a game in hand.
"I thought it was a very Hearts-like performance on Saturday," ex-Hearts player Halliday said on the BBC's Scottish Football Podcast.
"I think that's the third straight 1-0 victory at Tynecastle. Hearts have been that side throughout the season that, once they go ahead in games, it's very, very difficult to then come back and take points off them because I don't see an area of weakness.
"They've got goals throughout the team, Claudio Braga and Lawrence Shankland are in the top four goalscorers in the league, they're really strong in the middle of the pitch, whether it's Cammy Devlin, Beni Baningime, Marc Leonard or Tomas Magnusson.
"And for me, at the back, they have been absolutely outstanding all season long, Craig Halkett and Stuart Findlay. That's without even mentioning the guys that they've got in the flanks, Harry Milne and Alexandros Kyziridis.
"I just don't see a weakness they've got. They've scored goals in the last minute, they're great defensively, good going forward, they've got the best set-piece record in the league.
"So that's the reason why for a long period of time that I've felt as if they're the real deal."
