The Chilean produced a catalog of blunders, but still managed to finish on the winning side today.
Guardiola said of his goalkeeper: “What Claudio did was one of the best performances I've ever seen. I like goalkeepers to play in front and after that [United] goal, he continued playing in our build-up, playing long balls and coming out to pick it up.
“In football, it's about how you react to mistakes – it shows character. He continued playing. It means a lot.
“The way we train and the way we play has given me a lot of confidence.
"We played good in the first half because of Claudio. I like the keepers to attack the ball and after what happened, in the second half he continued to play and that's a good thing about his personality. He was one of the reasons we played well in the first half.
"Yeah [if you pass the ball from the back] it can be too risky; if you lose the ball they will score but you can control the game.
"Until my last day in England I will try to play with the ball as much as possible. I know it's impossible for 90 minutes but I'm sorry, I will not negotiate that.
“Today we made a lesson with the ball."
