I don't really understand the beef people have with Giggs' comments RE: Swansea.
They're in a bit of a free-fall, have regularly sold their best players, and have gone through 3 managers in 2 and half years, one of which was in his first job in management and as far as many people were concerned, was doing a decent job. People seem to be taking the ambition comment as a comment on Swansea's ability to compete at the top, but that seems highly unlikely and very unrealistic. It seems far more reasonable that the owners want someone on a short-term deal to come in to stabilise the club and keep them up this season, with no guarantee that they'll be kept on afterwards and investment being entirely results dependant, whilst Giggs is looking at something with a bit of longevity and board backing where he can make a name for himself.
If Giggs is serious about management then he's going to want to be one of the best around, and I don't think a job at a relegation candidate is really the best place to kick off a career. Guardiola had a single season with Barca B before taking over the senior side, and Zidane had just two with Madrid's B-team before taking over there. Mourinho hadn't managed anywhere before taking the Benfica job, and Klopp was able to walk into the manager's position at his last playing club and was then afforded time and patience to learn his craft. Even Ancelotti had a fairly kind start to his career, taking over a recently relegated and Reggiana and sending them straight back up, before taking over at a successful Parma side the next season. I can't really think of an active top manager, or at least not one who's come to the fore over the last decade or so, that started their career after a season was underway, at a relegation favourite.
Giggs isn't fortunate enough to have come from a club with a B-team in the division below, nor has he come from a club that has never played in its nation's top flight. He's got a bit of experience now as an assistant manager, and by all accounts wasn't even planning on taking a job this season. All he's known in his playing career is success at the top of the game, and for good reason, probably considers himself unsuitable for a position that requires him to save a struggling team, because it's something he's simply never experienced.
It's all well and good plucking out random teams looking for managers and going "BUT WHAT ABOUT THIS TEAM, RYAN!", but when those teams are Premier League relegation candidates Swansea City, Championship relegation candidates Derby County and Aston Villa, and League Two relegation candidates Newport County, but you're not proving anything other than he's clearly looking for a decent club and a fairly comfortable job to start his career, as many other top managers have enjoyed.
