Four games left: The Scottish Premiership run-inThe Scottish Premiership produced another thrilling weekend and there are now just four games left in a three-way tussle for the title.This time it was Rangers who slipped up, suffering a late defeat at home to Motherwell while Celtic beat Falkirk and Hearts' numerical superiority eventually told in the Edinburgh derby against 10-men Hibernian.It's Hearts who remain top of the league, three points ahead of Celtic and four above Rangers but there is still a lot of football to be played including what could be a final-day title decider.So, who will end up champions in this unforgettable 2025/26 Premiership campaign? Let's have a look at each team's run-in.RangersMay 4th: Hearts (A)May 10th: Celtic (A)May 13th: Hibernian (H)May 16: Falkirk (A)We'll start with third-place Rangers after their loss to Motherwell, ending a run of 16 games unbeaten in the league.On paper, this looks like the toughest of the lot although one that very much keeps them in the title hunt should they defeat their rivals. However, both games are away from home with the only game at Ibrox in the run-in when they host Hibs on May 13th. If Hearts are still top of the league by then perhaps Rangers may hope for an easy time of it.Everything rides on those first two fixtures for Danny Rhl's side though.CelticMay 3rd: Hibernian (A)May 10th: Rangers (H)May 13th: Motherwell (A)May 16th: Hearts (H)Moving on to the closest team to Hearts, Celtic, where home advantage could prove crucial by the end of the season.Celtic Park hosted the Old Firm derby on May 10th and then Hearts on the final day of the season. Victories in those two games could go a long way and may see the Bhoys turn what started out as a disastrous season into another successful one.One potential banana skin? Motherwell away.HeartsMay 4th: Rangers (H)May 9th: Motherwell (A)May 13th: Falkirk (H)May 16th: Celtic (A)History will be made if Hearts manage to stay ahead of the two Glasgow sides and Derek McInnes' side have looked more fragile in recent weeks as the toll of a title challenge takes hold.However, it's all in their own hands and Hearts would no doubt get a massive confidence boost if they can defeat Rangers next, which would essentially reduce it to a two-horse race with Celtic.The Jambos won 2-1 at Celtic Park back in December when the Bhoys were still managed by Wilfried Nancy. It will be tougher this time but that could well be the day that the 41-year Old Firm grip ends.
