Brendan Rodgers has claimed that Celtic showed a different side to their game in grinding out a goalless draw against Rosenborg in the second leg of their Champions League second qualifying round tie.
The Hoops produced a commanding performance in the first leg at Parkhead last week to take a 3-1 lead to Norway, before putting in a disciplined performance to see the tie out at the Lerkendal Stadium on Wednesday night.
"It was a great demonstration that you can't always play perfect football, especially away in Europe, when you are under pressure and there are questions asked about your resilience and I thought we stood up to that very well," Rodgers told reporters.
"It was a clean sheet and that is always good in Europe away from home. We won the tie last week with a great attacking performance and defended well and last night it was more about being solid and keeping a clean sheet.
"We have achieved the objective, which over the two games was to get through. It was a different type of game to last week. We couldn't quite build the game as well as we would have liked but I was very pleased with the way we defended – that resilience and mentality."
Up next for Celtic is a third-round qualifying tie against AEK Athens, with the first leg at Parkhead next week.
