Steven Naismith was pleased with the impact of his new Hearts signings after the cinch Premiership outfit breezed into the quarter-finals of the Viaplay Cup with a 4-0 win over Partick Thistle.

Rangers loanee Alex Lowry finished the match with two assists to his name, right-back Odel Offiah scored on his debut and second-half substitute Kyosuke Tagawa notched his first goal in maroon to seal an emphatic win over the Jags.

Offiah was the pick of the bunch and technical director Naismith was delighted to see his latest signing settle into his new environment so quickly.

“Yeah, but that’s why we signed him – he’s a good player,” Naismith said.

“He is somebody that we thought could come in and really contribute, and he’s different to what we have already got in the building for that position

“He has probably got a more mature head on for where he is in his career and he is a good footballer. He is desperate to learn, he’s desperate to get involved and it’s great to have him here.

“I think Calem [Nieuwenhof] had a good game and Alex Lowry had a better performance than he has had recently.

“Kenneth Vargas came in as well and they are all young players who are desperate to get better. They have all shown up really well in what could have been a tricky tie.”

Thistle manager Kris Doolan, meanwhile, new his side were always going to be in for a difficult afternoon but was still left disappointed by the nature of his players’ performance.

“It was a difficult afternoon, as we thought it would be,” he said. “We did not come here under any illusions that it was going to be easy.

“I was here during the week at the Rosenborg game. I looked at their bench that night and they had a full team that could have changed. But we didn’t help ourselves. We gave goals away and really good chances.

“If you do that at any Premiership side, you’ll get punished. If you do that at Championship sides, you’ll get punished. It’s not like us to gift as much of that. 

“Some of that hands to go down to Hearts. They stifled us at times. At half time we spoke about the need to come out and start positively.

“Then we gave away a third goal which is not like us. We don’t normally gift them as easily. We can’t continue to do that. We need to put a line under that and be better next week.”
