The Peruvian striker has returned to Bayern for the second time in his career after spells with Chelsea and Werder Bremen, and he has only one aim on his mind - to win more titles.
Bayern finished runners-up to Borussia Dortmund in the Bundesliga last season, while they missed out in the final of the DFB-Pokal to the same rivals and lost the final of the Champions League on home turf to Chelsea.
Pizarro, who won a league and cup double three times for Bayern, as well as winning the FIFA Club World Cup, wants to add to his collection of medals while lifting his new team-mates out of the gloom.
"I want to win everything - everything that there is, that is the aim," he said.
Pizarro returned to Munich to start pre-season training earlier this week and, although he spent six years with the club before moving to the Premier League in 2007, he says quite a lot has changed in the intervening years.
Nevertheless he knows "most of the people, the club and have always said that Bayern is the best club I have ever been at".
And he insists he has not returned to Bavaria just to play out the end of his career at the age of 33.
With Mario Gomez set to be Bayern's number one striker again this year, and with competition from Mario Mandzukic, Pizarro is aware he will have to fight for a piece of the action.
"But competition for places is normal" he said on the club's website. "You have that in every club.
"Back then (in 2001), we were five strikers so it was much more difficult then."
