Chris Martin believes he has reached the next step in his international career by feeling comfortable in the Scotland squad.

The striker, who has nine caps and two goals for his country, still believes there is more to come from him when he pulls on his Scotland top.

Martin, who represented England at youth level, first joined the Scotland set up for the 2-2 draw with Nigeria in 2014.

He has since made two competitive starts for Gordon Strachan's side and scored on both occasions - against Gibraltar and Malta.

Speaking ahead of Scotland's World Cup qualifier against Lithuania on Saturday, Martin says he feels at home with his international team mates now.

"The familiarity of it, playing more often and getting more minutes on the pitch - it makes you feel like you belong here," he said.

"I think that's the challenge when you first come into the squad, generally you're not always playing straight away and that was the case for me. I had to try and force my way into getting more and more minutes, and I feel comfortable here now.

"Hopefully that will show in my performances. That was the next step in my international career."

Martin will face competition this weekend from Steven Fletcher, Steven Naismith and Leigh Griffiths who are also fighting for the striking position.

He's hoping the national boss sees something in him that the others can't offer and ultimately add to his goals tally for this campaign.

"Every player brings their own thing to the table, hopefully I can prove that to the manager both in games and in training," he said. "If he sees fit to go with that option then I'll be right there.

"I think I've done ok but there's still more to come from myself. I've had a few opportunities now, done ok in some and not so well in others. It's trying to find that consistency in my performances and if I keep getting picked then hopefully that will come.

"I wasn't expecting it [to start against Malta], there were other people in line who were just as deserving. Leigh Griffiths was unfortunate with his injury, especially after the start to the season he's had and how he played last season. I didn't expect it to happen so that's why I think I was fortunate."
