PSG have been splashing the cash over the past few seasons and took things to another level when they smashed the world transfer record to sign Neymar from Barcelona in the summer for £200m.
They then beat Bayern 3-0 in the Champions League in September, but the Bavarians gained revenge last night and Muller says it is a reminder of their long-standing European pedigree.
"I think we won 3-1. Of course, PSG had one or two good chances but you did not feel that another team was superior to us here," he said. "We are still Bayern.
"When it was 3-0 in Paris, we had a corner ratio of 18-1 for us and it is pretended that PSG had a potion or something. Of course, they have very good offensive players but you should be off the gas when it comes to talking up other teams."
