It seems Danzo never used his Izanagi before. Also, like Hiruzen, he was already pretty damn old. Together with the fact that he expected to fight Tobi afterwards, i think the deck was stacked against him before the fight had even begun.

Also, his overreliance on checking the amount of eyes was what defeated him in the first place. Had he hidden the arm, it would've been much more difficult for Sasuke to figure out the trick.

Finally, had Danzo been quicker, he actually could've won the fight because he had Sasuke in a pinch, but took too long.
