Jose Mourinho described himself as humble in his first news conference as Spurs boss, saying he spent his time away from football analysing his career.
"I realised I made mistakes," he said.
"I'm not going to make the same mistakes. I'll make new mistakes - but not the same."
Mourinho, who would not be drawn on what mistakes he was referring to, added: "I am humble, humble enough to try and analyse my career - not just the last year, but the whole thing, the evolution, the problems and the solutions. Not to blame anyone else.
"It was a great thing. I went really deep with that analysis. A break was very positive for me. It was the first summer I did not work and I felt a little bit at a loss during that pre-season.
"I was always humble, in my way. The problem is you didn't understand that."
