The Spain international is pleased to see his former coach return to the game, and has little doubt he will prove to be a success at the Bundesliga leaders
The 42-year-old recently signed a three-year deal with the Allianz Arena side and will replace Jupp Heynckes at the helm at the end of the 2012-13 campaign.
"I am happy for Pep. It's important for football and for himself that a coach like him is training a club. He will try to get his new players used to his playing style. Bayern have some great players," Iniesta was quoted as saying by Bild.
"I believe Pep will hold on to his own style. Bayern's playing style is quit similar to Barcelona's style. Possession is quite important, plus they have a number of players of the highest level.
"Pep always gives 100 per cent in what he does. He is very close to his players, both on and off the pitch. It will be something great for the Bayern players. The fans can also look forward to him, something wonderful will happen.
"I don't expect any difficulties. He will take charge of a great club and try to win the people's respect. I have no doubt that he will succeed."
Guardiola is currently enjoying a one-year sabbatical away from the game after leaving Barcelona last summer.
