The Rovers boss helped the club to the Premier League title in 1995 but was then part of the team that had a disappointing campaign in the Champions League.
The Ewood Park outfit claimed only four points from a group including Spartak Moscow, Legia Warsaw and Rosenborg.
“Good!” laughed Berg, who played in all six group games during the Champions League campaign.
“It is strange that has happened the first time Manchester City won the league and it happened to us as well.
“After we won the league we were not as mentally able as we should have been in terms of coping with winning the league - making sure we had the right attitude, the right squad and the right play to have a really good year afterwards.
“We didn’t have that experience as a club and as a team.
“I think City are a bit more further forward than we were at that time in terms of the squad we had but in terms of mentality they might find it a bit more difficult now that they have won the league and expectations are much higher.
“And they ended up in one of the best groups ever in the Champions League.”
