The 30 year-old, who is due to return to action this spring, took on the feared Mexican last May to raised eyebrows and was duly wiped out in the sixth round of what was a back and forth contest to that point.
A long-time hand injury also hampered Khan, not only for the Canelo bout but others prior to the Vegas headliner, and the Briton is confident about the future as he prepares to test out the newly-mended fist.
“I don’t care about criticism about fighting Canelo,” Khan told The Bolton News.
“I did it for myself – I wanted to prove to myself I could win that fight. Obviously I didn’t but any doubters don’t get to me.
“I know I can win a world title at 147 and people will forget about the defeats. Even though I only had the one fight and it was a loss, there are still some good things that have come from the year.
“It has been tough and not been easy mentally to get over the hand injury. It did scare me a bit because my hand was hurting a lot. It was playing on my mind in every fight.
“It used to hurt me and I knew it needed fixing but I was too scared to get it fixed because, God forbid, it doesn’t go right and then my career is ruined really.
“It was a big risk to take but not being able to punch fully without it hurting was weighing on my mind. It is done now and I’ m happy and feeling good as well.”
On his future and whether he intends to stick around, Khan added: “I have still got a couple of fights left in me and cannot wait to be back.”
Khan could meet UK-rival Kell Brook in an April or May blockbuster in London, although WBN has been informed that talks between the pair have slowed down over the holiday period.
