The French winger promises no respite for the Catalans despite his side carrying a 4-0 lead into Wednesday's Champions League tie, demanding another top-class performance
The Bavarians go into Wednesday's Champions League semi-final second leg on the back of a devastating 4-0 win over the Blaugrana, warming up for the fixture with a 1-0 victory against Freiburg on Saturday.
However, despite progress to the final looking reasonably assured, Ribery warned the Liga leaders that Bayern would not be taking anything for granted.
"We are not done yet," the 30-year-old Frenchman was quoted by tz-online.de. "It is very difficult at Camp Nou. We have to play like we did in the first game."
The former Olympique de Marseille player's thoughts about continued focus were also echoed by Bayern director of sport, Matthias Sammer.
"The focus in Barcelona should be on the performance and not on the result," the 45-year-old stressed. "We just have to carry the ball as we did in the first leg and play with creativity. If we don't do it that way, it could be dangerous."
Die Roten have enjoyed an excellent season and Emre Can's goal against Freiburg was enough to take them to 84 points, breaking the Bundesliga points record with three games still to play.
"It's a wonderful achievement," Sammer enthused. "I am really happy about it. This is very important for the head, for our rhythm and the mood in the dressing room.
"The season has been a marathon. We've already won the championship. In the Champions League we are very much in the hunt but we're not yet at the destination."
