The Scottish champions managed to record a 1-0 home win in the third round of Champions League qualifying, thanks to Commons’ 76th minute goal, and the 29-year old believes the Swedes prepared just as the Glasgow giants did for Barcelona last season.
"It reminded me a lot of how we played against Barcelona. We had to give their top-quality players respect, get behind the ball and make us break them down,” said Commons.
"In fairness to them, they probably saw how good we are at home and gave us respect. They would have been happy at 1-0.
"It could be a vital goal in the grand scheme of things but I do think we can score in Sweden. (Goalkeeper) Fraser (Forster) could have stayed in the changing-rooms. I don't think the ball touched his gloves.
"They were happy at 1-0. I think they would have been delighted at 0-0. But we are more than confident about going on the road and getting goals."
