But if the Czech Republic defender was impressed by the 30,000 who made the effort on Thursday evening, he will be overcome when he starts the new season and the "house Full" signs are up at St James'.
The former Paris St-Germain star appears to be a certainty for the starting line-up at Bolton when the new campaign kicks off on August 11th.
Rozehnal Has Seen 'Nothing Yet'!
Rozehnal: "I was a little bit nervous, but it was a healthy feeling to have.
"It was my first home game and there were a lot of supporters out there. It was a nice atmosphere, and a nice pitch.
"I tried to do my best and to show to my team-mates and the coach that I can be the right man in the right place.
"Now it's up to the coach how he will choose his team.
"I thought it was a good game for us. We won, which was the most important thing.
"It was also important that we played a good game as a team. We stayed compact, defended very well and scored a lot of goals against a big team in Celtic.
"I think it was a good match, but we must keep our feet on the ground. We have to continue working hard, and stay focused on the first game of the season.
"As the coach said after the game, the most important thing is to keep a clean sheet and then try to score.
"If they had scored when it was 0-0, the game would have gone away from us, so we can't concede like that.
"This will be key for us in the Premiership."
