Derek McInnes was thrilled after his Kilmarnock side edged closer to securing European football with a confident victory over St Johnstone.

Killie deservedly took the lead midway through the first half when Joe Wright turned home Liam Polworth’s pin-point delivery – and the visitors were denied on multiple occasions to extend their advantage by the heroics of Dimitar Mitov.

The game was settled with nine minutes remaining after Marley Watkins tapped home his 13th goal of the season.

Kilmarnock have extended their advantage in fourth place to eight points, with just five games remaining.

“I thought first half we were very good,” McInnes said.

“Coming away from home, we tried to impose ourselves. We spoke throughout the week about the importance of matching their motivation.

“We knew we were up against a team with so much riding on the game, we had to match that and a bit more.

“I was bemoaning the fact we didn’t get that second goal, which we maybe merited for our first half dominance as an away team – to have that control was really pleasing.

“We never got started in first 20 minutes of the second half but thankfully we got the second.

“It’s not easy winning games in this league, especially away from home – we did a lot right and credit to our players.”

Despite moving one step closer to returning to Europe for the first time since 2019, the Rugby Park boss insists there is still work to do.

Kilmarnock have lost just one of their 11 Premiership encounters since returning from the winter break in January.

He added: “There’s still work to be done and hopefully a few more special days to have.”

Craig Levein felt his team failed to hit the heights of recent performance during a lacklustre showing.

Saints were unable to build on their excellent victory against Hibernian at Easter Road as they slumped to defeat at McDiarmid Park.

St Johnstone remain 10th in the table and look set for a battle to avoid the play-off position in their post-split fixtures.

“The rollercoaster is back in operation. It was a hell of a frustrating afternoon,” Levein said.

“After the last two games I’ve been talking fairly confidently about continuing at that level.

“We didn’t play with the confidence I thought we should’ve done because of our previous performances.

“Individually we didn’t have that many players who played anywhere near their best.

“Kilmarnock didn’t batter us by any stretch of the imagination and we had some good chances.”

Kilmarnock continued their European surge after a comfortable 2-0 victory over St Johnstone at McDiarmid Park.

Joe Wright opened the scoring midway through the first half, and Derek McInnes’ side could have been out of sight had it not been for the heroics of Dimitar Mitov.

The game would be put out of reach with nine minutes remaining when Marley Watkins tapped home his 13th goal of the season.

Killie have moved eight points ahead in fourth spot in the cinch Premiership, while their hosts remain in a battle to avoid the relegation play-off after another poor home showing.

Kyle Vassell took his goal tally for the season to 10 last weekend and he really should have opened the scoring after getting on the end of Danny Armstrong’s cross in the second minute.

The ball dropped nicely at the feet of the striker, but he failed to make a proper connection, resulting in an important block by Dan Phillips.

It took a brilliant challenge by Andy Considine to prevent a potential breakaway after Luke Robinson carelessly surrendered possession to Vassell.

St Johnstone had failed to create anything of note going forward. However, Matt Smith’s wind-assisted cross almost caught out Will Dennis.

Kilmarnock made the breakthrough on 23 minutes, Liam Polworth sent over a tantalising delivery, which Wright stretched to turn beyond Mitov from six yards.

Armstrong went close to doubling the visitors’ lead with a free-kick that narrowly missed its mark, while at the other end, Robinson worked Dennis after a positive forward run.

The chances kept coming for Killie. Watkins was denied by a smart stop from Mitov, before Matty Kennedy’s quickly taken corner struck the face of the crossbar with the Saints keeper still organising his defence.

Mitov was having a busy afternoon and was called into action again when Watkins latched on to Armstrong’s clever through ball.

Craig Levein’s side looked brighter after the restart. David Keltjens sliced over, then Max Kucheriavyi stung the palms of the keeper with a curling strike from the edge of the box.

They were almost punished for their lack of cutting-edge however, as Stuart Findlay struck the side-netting after a rare lapse of concentration by Mitov.

It required a tremendous goal-line clearance to prevent Watkins doubling Killie’s lead with 23 minutes left on the clock.

The loose ball then broke the way of Polworth who fired a goal-bound effort that Mitov brilliantly parried around the post.

There was another scare from the resulting corner for the home side, Liam Donnelly rose highest to connect, but the home keeper produced more heroics to keep the deficit at one.

After surviving an onslaught, Saints almost got back on terms when Dennis somehow pushed Ryan McGowan’s close-range shot on to the post.

With nine minutes remaining, Killie finally got the goal their pressure merited.

A well-worked set-piece routine saw Findlay nod Armstrong’s delivery back across goal – and Watkins was left with the simple task of knocking home from a yard out.

Benjamin Kimpioka tried his luck with an acrobatic attempt that crept over the crossbar, rounding off a disappointing afternoon for the home side.

Celtic manager Brendan Rodgers hailed the “excellent” Kyogo Furuhashi after the recalled striker scored and provided an assist in a 3-1 win over St Johnstone.

The Japanese forward also had two goals disallowed for offside as Celtic moved back to the top of the cinch Premiership, at least until Rangers face Dundee at Dens Park on Sunday.

Furuhashi has been unable to replicate the prolific form he showed under Ange Postecoglou last season but was back in the team following three consecutive substitute appearances and took his tally to 16 this term.

He headed home a 40th-minute opener after beating goalkeeper Dimitar Mitov to Nicolas Kuhn’s cross and then set up the German winger to score in the opening minute of the second half. He also hit the crossbar and generally looked to be at peak sharpness.

“Adam (Idah) has been very good when he came in and that is what Kyogo and every player needs,” Rodgers said. “They need competition.

“But I thought he was bright, his movement was good. Sharp.

“He was very brave at the first goal. He makes a run and comes back onside and obviously some strikers would maybe move their head out of the way with the keeper coming through but he didn’t and he scored the goal.

“And it was a great cross for the second one. He was excellent.”

Kuhn netted his second goal for Celtic and continued to impress following a fruitful first start at Parkhead against Livingston last weekend.

“I think you are starting to see a little bit of why we brought him here,” Rodgers said. “He’s very quick.

“It was just hard for him when he came in, struggling with his teeth and everything medically. But he has shown now that he has his strength back up and he’s training really well.

“He obviously puts in a great cross for the first goal and you see his speed for the second one.

“We always want our wingers to get in the box. He got himself in there and scored a fantastic goal.”

Substitute James Forrest added a third and Alistair Johnston was denied a goal by a marginal offside call after Connor Smith had pulled one back for Saints, after Celtic defender Cameron Carter-Vickers had gone off for a rest.

Rodgers said: “I thought from the start of the game there was a great feeling in the stadium and from the crowd.

“The players started the game well and I thought overall it was a very good performance.

“The only downside was when I made all the changes our pressing went a little bit passive and that gave them a little bit more time on the ball than we would have wanted.”

Saints manager Craig Levein admitted his side could not produce the complete display they needed to get another result at Celtic Park, having drawn in August.

“Our defensive display was really good,” Levein said. “Losing the goal early in the second half was a killer blow but in the first half we restricted Celtic to very few opportunities.

“When we had the ball we just coughed it up every time. It seemed to be constant that we turned the ball over and invited Celtic to have another attack. That was the frustrating part.

“It was about half-an-hour until Celtic had their first shot on target. We restricted them to the wide areas and managed to block any shots and crosses.

“But if you continually give the ball away to a team as good as Celtic, you’re going to be facing attack after attack.”

Levein lost midfielder Sven Sprangler to a knee injury midway through the first half.

“It looks like Sprangler has opened his medial ligament,” he said. “I’ve no idea if he will be out for weeks or months.”
