Najdorf's book, written in Spanish and published in Argentina in two volumes, has long been known as a classic amongst Spanish speakers. It has also become a bibliographical rarity, and chess book dealer Tony Peterson tells me that one is unlikely to be able to source a copy for much less than £100 these days. However, the linguistically-challenged English native speakers can now get the first English translation of the book, published by Hanon Russell.
I have only had the briefest of glances at my copy, but that is enough to see that it is great, and certainly a worthy rival to Bronstein's book. The notes are generally much more detailed, especially in terms of variations; Bronstein relies much more on general prose explanations, which are certainly highly instructive in places, but Najdorf's notes are much more concrete and supported by specific variations. He also brings a lot of flavour to his commentary, reflecting Najdorf's own colourful and witty personality. The book is fabulous and a must for every chess lover's bookshelf.

The blunder at move 22 makes things easy for White, but Black was worse anyway:
