Martin O’Neill is adamant that Celtic’s determination to clinch the title is more intense than ever following their triumph in Dundee, which brought them within a mere three points of the league leaders, Hearts.

Previously, Celtic had faced setbacks in Dundee, losing all three encounters this season—twice against Dundee United and once against Dundee.

Their latest defeat in the city occurred just two weeks ago, when Celtic fell 2-0 to Dundee United, leading O’Neill to question his team’s resolve in the championship race.

However, with Hearts stumbling earlier in the day by drawing 2-2 at Livingston, Iheanacho’s decisive goal with just 10 minutes remaining narrowed the gap to the top, leaving six matches left in the season.

“For the first time, a couple of weeks ago, I had to ask whether we truly wanted it,” O’Neill remarked, urging his squad to mentally reset after their loss at Tannadice.

Celtic boss Martin O’Neill says his players have reset their attitude ahead of the title run-in

“Regardless of the playing field, in the second half, I felt we lacked the drive to engage in the match. The second goal really set us back, and we struggled to create any significant chances throughout,” he added.

‘Then you have a fortnight to think about it, so we’ve come in with renewed determination, try to get in front today and try to naturally take the game away from Dundee.

‘We did that today, we’re still in it and still have a lot to ponder. Did we reset our attitude? Absolutely, I think we did and I think that was to do with the way we approached the game right from the off.’

O’Neill’s side were much-improved from what they served up a fortnight ago across the road, showing much more attacking intent throughout.

Yang had given them an early lead, before Simon Murray equalised for Dundee from the penalty spot to tee up a nervy final half-hour.

But it was a test of character that Celtic passed, with substitute Iheanacho coming off the bench to fire the winner with a little under 10 minutes to play.

On the importance of the win, O’Neill continued: ‘I think that if we had dropped points today, it would have been a long, long way back. I’m not saying it was finished, but it was a long way back.

‘But given the fact that Hearts dropped a couple of points today, the games are difficult. They are honestly, they’re really difficult.

‘So we need to try and beat St Mirren next week so that you go into the split – I think we’ve got three at home and two away.

‘But there’s no room for us [to slip up]. It seems as if there’s never been any room for us. But if we had dropped points today, I think that would have been a long way back for us.

‘We carved out chances and when the second goal didn’t come, maybe it’s just the pessimistic side to me, but I felt it might come back to haunt us.

‘Dundee got the penalty, the resurgence of confidence, so it was tough. But we had to try to do something because a draw was no good for us. Thankfully, we got there in the end.’

On Iheanacho scoring the winner, O’Neill added: ‘He has had some issues with injuries. At 29, he should be at the peak of his career rather than sometimes scratching around.

‘He scores, he can hold the ball up and is really good at that. He maybe can’t run the channels much but at the end of the day he can hold the ball up and that’s his trademark.

‘He’s played for Manchester City, some time ago like everything else. But that goal will do him the world of good.’

Despite the experience of the likes of Callum McGregor, Kieran Tierney and some of the other senior players, O’Neill believes this is uncharted territory for many others in the Celtic squad.

Especially given the manner in which they have often had the league title sewn up by the time they reached the split over recent seasons.

‘We do have a couple of players with experience, but we’ve actually got a couple of boys who haven’t been over the course,’ he said.

‘You make an interesting point because this time last year, Celtic were cruising, you know, and had been cruising for a number of years.

‘This has been really tight for them. So this is kind of – even though we’ve got some experience in the side – it’s a kind of a new experience for these lads.

‘To be chasing and chasing and chasing, you know, and being under pressure to get results all the time.

‘But if you’re thinking about the likes of Callum [McGregor] and people like this here, yeah, I think that the younger lads would want them to be leaning on someone like him.’
