The former Germany international believes that people should not expect so much from the former Barcelona boss after his year-long sabbatical from the game
Great things are expected of the former Spain international, who is credited for the creation of one of the finest teams in history during his four-year spell in charge of Barcelona.
Fink has a lot of time for Guardiola but he feels that the sense of expectancy surrounding the 42-year-old's arrival in Bavaria is threatening to get out of hand.
"We often played against each other," the ex-Bayern midfielder told Bild. "And when I was a coach in Basel, we have met twice on the elite coaching course.
"But the hype around him is certainly not easy for him. Even Pep is only a man and did not invent football."
Fink will have the opportunity to pit his wits against Guardiola on Saturday when their respective sides face off in a friendly and the 45-year-old is looking forward to the challenge.
"We will not hide like a rabbit caught in the headlights and only play on the counterattack," he promised.
Fink won four Bundesliga titles and a Champions League during his time at Bayern as a player.
