Former Rangers midfielder Kevin Thomson believes it would be a remarkable story whoever wins the Scottish Premiership title, but thinks Celtic's home advantage on the final day could prove pivotal.

Martin O'Neill's side trail Hearts by three points with four matches remaining and they host the Tynecastle outfit on the final day of the season.

Hearts play Rangers next Monday, while Celtic travel to Hibernian on Sunday.

"They've all actually got their own wee story of success - when you think of Hearts, it would be an astronomical achievement if they can go on and win the title," Thomson said on the BBC's Scottish Football Podcast.

"Celtic have sacked two managers this year, Martin O'Neill's had two different stints as interim. If he can find a way to get his Celtic team to get over the line.

"When Danny Rohl took over from Russell Martin, nobody gave Rangers any chance.

"So it's amazing - the climax of the season has been so exciting. I cannot call it.

"I would never write Celtic off because I'm not naive enough to. I've never done it as a player. I certainly wouldn't do it as a pundit or as ex-player.

"But I certainly do think, if Hearts can beat Rangers, regardless of what Celtic do, I think it puts Rangers to bed and then it becomes a two-horse race.

"The advantage that Celtic would have is home advantage when that game comes around.

"The good bit from Celtic's perspective is they're still hanging in there. They're still there, they've still got a chance and they've not been at their brilliant best by any stretch of imagination."
