If he had made those comments I probably wouldn't much like it, but I can put the trust in him because he's got history to show for it.
It's really rather simple - if a manager who has won the league at every club he's managed comes out and says something like that you have a reasonable amount of faith that he knows what he's doing.
If a manager who has just a few months under his belt, no trophies and no coaching badges, comes out and says it you wonder whether or not he knows what he's doing - and whether the players will have respect for him after those comments.
Your post is contradictory in the sense that you are basically saying people shouldn't speculate about LvG, but then come out and directly compare Sherwood's treatment with what you speculate is the treatment he would get. But you are essentially comparing a university student with a 30 year senior and qualified professional. If you go into a hospital, whose opinion are you more likely to rely on, the student Doctor or the eminent surgeon who has conducted 20,000 operations?
Tim has nothing to show in managerial terms, but he
has won the Premier League, something our squad are far from capable of. For what he lacks in tactical nous, he makes up for in on-the-pitch experience and know-how. The players should respect him in such that he has done something none of them have but they should be striving to do. In my opinion, if
any of our players are not giving their all due to Tim's CV, they can be released on a free as far as I'm concerned, from a fans' point of view.
To suggest Van Gaal
knows what he's doing when he criticises players would be naive - he has cost himself several jobs doing so.
You mention LvG's history, but I notice everyone is cherry-picking his achievements and paying particular attention to his win ratio (something we know is not enough as AVB's was more than acceptable).
He managed Ajax for several years, taking over in a league heavily dominated by 2 teams until very recently (similar to the SPL until the Rangers fiasco). I would not attribute championships in the Eredivisie to being a top manager (after all Steve McLaren won it!), but a good start none-the-less.
Barcelona, again a league heavily dominated by 2 teams, but he broke a 3-year absence from league titles with them. Lost the title in his 3rd season to Deportivo La Coruna following a few high profile fall-outs with star players, in particular Rivaldo.
Took over as Netherlands manager - failed to qualify for the 2002 World Cup, finishing behind Portugal and Republic of Ireland.
Back to Barcelona in summer '02, but gone by January '03 with Barcelona sat 3 points off relegation.
Takes role of Technical Director at Ajax in '04 but resigns same year due to internal conflict.
Manager of AZ Alkmaar. Finishes 2nd, 3rd, 11th, 1st. Again, Eredivisie not comparable to the Premier League.
Bayern Munich, won the league title first season, something they had done 8 of the 12 previous seasons. Also won DFB Pokal.
Sacked in April the following season having dropped below 3rd place in the Bundesliga.
Back at Netherlands - remains to be seen how they will fair in Brazil.
He didn't win the Champions League with either Barcelona or Bayern Munich, could that be seen as an under-achievement by their standards? It certainly is these days, and they were equally as dominant back then.
Admittedly a brief breakdown, but it's hardly all unicorns and fairy tales. If he did come to manage us, it'd be the first 'project' of the sort. AZ are the only time he hasn't managed a club expected to win the league, and that league is not comparable to ours.
I don't deny LvG has far more on his CV to shout about, but does that automatically make him more suitable for us? I don't think so. In fact, you could argue he is as much of a risk as Tim is, given his inexperience managing teams at our level, and
no experience of the Premier League whatsoever.
