Stuart McCall's assistant Kenny Black has told the Rangers official website that the 2-1 win over Hearts on Sunday was the best performance since they took over.
McCall, 50, was appointed Rangers boss in March, coming in as a replacement for Kenny McDowall as Rangers attempted to make a late push for second place in the Scottish Championship.
After two draws in the first two games, Rangers have finally hit their stride under McCall, winning the last three games, including a huge 2-1 win over Hearts on Sunday afternoon.
Goals from Kenny Miller and Haris Vuckic gave Rangers all three points, defeating the team who have already been crowned Scottish Championship title winners.
Now above Hibernian in second place, Rangers look like they're tightening their grip on a crucial play-off spot - and recent results have shown just how good they can be.
Speaking to the Rangers official website, assistant manager Black admitted that he told McCall the display against Hearts was their best of their reign so far.
"I said to Stuart after the game on Sunday that our performance in the first half was the best we've had from the players since we came in," said Black. "The second half was more about having the determination to see the victory over the line and that was pleasing."
To beat such a rampant Hearts side at Ibrox was a big boost for Rangers, and fans will now be expecting to see similar displays and results before the end of the season.
