But, as confident the substitute was that he could get among the goals, by then he was expecting to net from the spot.

“When I was watching from the bench, I could see things were coming off Lee Miller up front and I thought that, if I got on and could get forward from midfield, there was a good chance I would get on the end of something,” said the 19-year-old.

“By the time I scored, though, I was thinking that we were going to penalties. I was definitely going to volunteer to take one, but it is not something you look forward to, so I’m glad we got the winner.

“It was a brilliant ball into the box and I’m just glad I put it in. I was a bit surprised I made the bench because I thought the likes of Stuart Duff would have been there ahead of me, but once I knew I was on it I just hoped I’d get my chance.

“I’ve had to wait since I came on against Falkirk on the first day of the season, but the manager has been brilliant and kept encouraging me to keep working for my chance.”

Robertson has now set his sights on further involvement when the Tangerines travel to Love Street to face high-flying SPL newcomers St Mirren on Saturday.

With Duff expected to come back into the reckoning for a starting place in that one, he may have to remain patient.

Striker Noel Hunt, meanwhile, is expected to be OK, despite limping off near the end of 90 minutes with a leg knock last night.

Hunt was in the wars last night and also gashed an arm, but should be fine in a day or so. Defender Lee Mair, missing for two games with a knee knock suffered in training last week, may also return to the squad this weekend.
