I seriously doubt that Contador lacks self-criticism.
Just because it doesn't transpires to the public (at least, 100% explicitly), it doesn't mean he's an arrogant man.
For example, he recognized his sub-par performance in 2013's Tour. Not only through words, but mainly through actions, hence arising his need to improve his training, diet and several other things, such as his cadence, which he did successfully in 2014 and in 2016.
Successful people are their own biggest critics. Because only through acknowledging their own mistakes they're able to perform and keep being the best (or one of the best).
What one can state is that Contador isn't the most honest rider, particularly when talking to the media. But again, he isn't paid to be honest to the public, but to win races.
