"There is nothing worse than hearing someone give reasons for why they've failed - of course sometimes there are reasons - but you have to take the blame yourself,"

"I cannot open that hotel and blame the general manager for it failing. Why? I appointed the general manager.

"I can't go to Spain for four months, be coach of Valencia, and blame the fact there was a difficult dressing room, I didn't speak the language, we had bad luck and we missed some chances.

"Why? Because I knew I didn't speak the language before I went, I knew it was a difficult dressing room, I knew they had sacked lots of managers and I didn't deal with it.

More interesting part of the article IMO. He did always say he didn't want to be a manager long term so it's not really surprising he's saying he might not coach again.
