Former Hearts and Rangers midfielder Andy Halliday suggests Rangers may have to "throw caution to the wind" at Tynecastle on Monday.
The Motherwell midfielder, who played for both Rangers and Hearts, feels Emmanuel Longelo's late goal against Danny Rohl's side last weekend has totally changed to dynamic ahead of Monday's game.
The sides had been level at Ibrox with 20 minutes to play on Sunday but Longelo's 90th minute goal took all three points for Jens Berthel Askou's team and pushed Rangers four points behind the league leaders.
With that in mind, Halliday says Rangers' title challenge will be over if they don't win on Monday.
"I think it's done for Rangers absolutely," he told the BBC’s Scottish Football Podcast.
"It'll then go to seven points between Rangers and Hearts with only nine points remaining. So they would absolutely be out of it.
"Rangers getting a point at home to Motherwell, you can't say it's a good result because they needed to win that game but I do think that that goal by Emmanuel Longelo in the last minute completely changes things.
"If that finishes a draw, then Rangers are only three points behind Hearts with a better goal difference going to Tynecastle. So even a draw in that respect, I still think they're in the race because there's three games to go. It only takes Hearts to lose one, Rangers to lose one.
"So I think that it's a game that Rangers have to win and it will be really interesting to see how they respond to that. If it is 1-1 or 0-0 with 10 minutes to go, for me I think they have to completely throw caution to the wind to try and win the game.
"Does that then suit Hearts to then try hit them on the counter attack with the likes of Pierre Landry Kabore that will no doubt come off the bench with his pace towards the end.
"I think it's going to be a fascinating game but without doubt it's one that Rangers have to win to stay in this race."
