Hearts boss Derek McInnes has warned that the upcoming encounter with Edinburgh rivals Hibernian may prove to be the most challenging fixture of their title chase this season. The Hearts side sit atop the Scottish Premiership, a solitary point clear of Rangers, and travel to Easter Road for the post‑split round of matches on Sunday, a game that will be broadcast live on Sky Sports. The Jambos have dominated the league for the majority of the campaign and now have five matches remaining in their pursuit of the championship – a triumph that would mark their first league crown since the 1959‑60 season. McInnes, speaking to Sky Sports News, described the Hibs game as "arguably our hardest game for lots of different reasons, Hibs away and the derby and everything that entails." He added that he is extremely pleased with the squad's performances that have positioned Hearts in this favorable spot.

"Like most things, whether it's a race or any title race, it's always the last few games that normally decide everything and that's where we are," McInnes said. "It's such an exciting situation for the three teams involved, but every team in the top six has got something to play for. Obviously you play the best teams now in the top six and there's a lot at stake for each team, none more so again on Sunday." Hearts currently enjoy the best head‑to‑head record against the other top‑six clubs this season, yet they suffered a defeat on their last visit to Easter Road back in December. McInnes is well aware that Hibs will be eager to dent Hearts' title hopes.

"Any Hearts‑Hibs fixture, regardless of where both teams are in the league, it's never meaningless," he explained. "A big aspect of their motivation in front of their home fans is not to let Hearts win the game, but you'd expect that and they've got to expect a tough game from us." The manager reflected on the tight nature of recent matches, noting that Hearts had been on the losing end of a close contest in their previous outing.

"Obviously, we took a sore one there in the last time out. We've got to learn from that and hopefully, as I say, we start better, we perform better over 90 minutes and hopefully we get a better outcome," he said. In addition to the tactical and psychological challenges, McInnes disclosed that key player Oisín McEntee will miss the remainder of the title run‑in after sustaining a hamstring tear during the second half of the 3‑1 victory over Motherwell earlier in the month. The versatile Irishman, who has been utilised across the back line and in midfield throughout the campaign, is now ruled out for the season.

"Oisín's out for the season unfortunately, so real bad news for us on that one," McInnes lamented. He also mentioned that Tomas Magnusson is dealing with a thigh tear, meaning the squad will be without two important contributors.

Despite the injury setbacks, McInnes remains optimistic about the fitness of forward Harry Milne. "Harry is progressing really well. He's touch and go for the weekend and we just need to weigh that up, how much work he does before the weekend, whether he gets involved or not. If he doesn't make this one, he should be in place for the next one against Rangers," the manager said, highlighting the depth of options at his disposal.

Looking ahead, McInnes emphasised that the final stretch of the season is where titles are truly decided. He praised his players for their consistency and resilience, noting that the team's ability to secure points against the league's elite will be decisive. "It's such an exciting situation for the three teams involved, but every team in the top six has got something to play for," he repeated, underscoring the competitive nature of the Scottish Premiership at this stage.

The upcoming derby against Hibs is more than just a fight for three points; it is a test of character, preparation, and the capacity to handle pressure in front of a hostile crowd. McInnes believes that Hearts' experience in high‑stakes matches will serve them well, but he also respects the passion and determination that Hibernian will bring to Easter Road. "A big aspect of their motivation in front of their home fans is not to let Hearts win the game," he said, acknowledging the intensity that derbies always generate. As the season reaches its climax, Hearts will need to maintain their composure, stay injury‑free as much as possible, and capitalize on any opportunities that arise.

The manager's confidence in his squad remains high, even as he navigates the challenges of player absences and the looming pressure of a title race that could be decided in the next handful of fixtures. Fans can look forward to a fiercely contested match on Sunday, with the outcome likely to have significant implications for the championship leaderboard. Whether Hearts can preserve their narrow lead over Rangers and secure the Scottish Premiership crown will hinge on their performance at Easter Road, making the derby a pivotal moment in what has already been a dramatic season.
