I never called him shite. Neither i called him a great manager.
When you're managing the big names such as England, Italy, spain or some other similar big calibre you're expected to win your qualifying group. Most of the times it's filled with cannon fodders like Andora, Lichtenstein and many other smaller nations. With all due respect.
Over the years we've had historically strong nation failed to make finals due to a myriad of reasons, mostly non technical reason or something that's beyond a manager scope of influence. We even had some manager whose normally successful failed to qualify. With England it happened under McLaren iirc. But most of the times, qualifying is never an issue, and most of the times getting out of your group is almost a given. But for the sake of argument, reaching a semi or final is normally a 3 match qualifying and last 32, 16, 8, 4, 2 that's like 8 total games to win the whole cup with the first 3 is normally considered an easy part...
So it's not out of the question that you can face a lucky draw playing against let's say Jamaica, or UAE, or even many other canon fodder that are spread around the groups due to seeding. A lucky draw means you had 1 free match to rest your players if you win your first 2, and comes to final 32 fresher than most.
So yes... As to my original comment, luck and many other factors played a bigger part in a considerably shorter tournament. It's hardly outrageous. We all know how the strongest team dont always wins tournament because they lost out when it matters. And he's not actually managing Andorra. He's managing England who's strong enough to handle 70-80% teams they faced, at least on paper.
