Arjen Robben and Thomas Mueller scored extra-time goals as Bayern won the German Cup with a 2-0 victory over rivals Borussia Dortmund on Saturday.
Guardiola finishes his first season in charge of Bayern with four trophies having already won the Bundesliga title, Club World Cup and UEFA Super Cup.
Having arrived in Bavaria with a glowing reputation after winning 14 titles in four seasons at Barcelona, Guardiola says the current campaign has been tough. "It's my fifth year as a coach and it's been the hardest year of my career," said Guardiola.
"My German isn't so good and coming in after (predecessor) Jupp Heynckes won the treble, wasn't easy for me.
Each trainer has his own ideas and I know the players were thinking, 'why do we have to make changes?'" Bayern lifted the German Cup for a record 17th time to claim the domestic league and cup double and the Champions League was the only title to elude them this season.
But Guardiola admitted he deserved criticism from the German media in the wake of their 4-0 home drubbing by Real Madrid in the Champions League semi-final, second-leg, and says Bayern must improve.
