Guardiola has stated defender Serdar Tasci proved him wrong, after his exceptional performance against Hertha Berlin.
The former Stuttgart defender was signed on loan back in February, due to the growing list of injured defenders at Bayern.
And Tasci previously stated he regrets the decision to join Bayern Munich, with playing time extremely limited.
And Guardiola was forced to admit that he has not been fair with Tasci after his impressive display in the capital.
“Serdar Tasci showed me how unfair I was to him,” he said, as quoted by Bild.
“It’s crazy how he played. It’s hard when you haven’t played a minute for the last two months.
“He’s a great personality, it’s a huge compliment to Serdar. He will really help us in this period of the season.”
