Champions League fixture against Galatasaray.
"It was a tough game," he admitted. "We started well and scored the goal. They had a few chances but I think we had more overall and, in the end, I think we were the better team and we deserved to win this game.
"I believe we were a bit nervous because of the experience of last year. Sometimes this mentality, this pressure can cause you problems as it did in the first half. In the second half, we responded a bit better, we had better chances and I think we should be happy in the end with the three points.
"We knew how important it was to win the first game and we did it. Now we can move forward and work on the next game."
