Ah the old "he hasn't proven himself at this level" shtick. Apparently you can win some of Europe's top leagues and reach 5 European finals, but it doesn't matter if you haven't proven yourself at Championship level.
And where has MON proven himself at Championship level? Half a good season at Norwich, which is similar to what Sven has done here. Followed by a medicore half season at Leicester in which he basically had mid-table form and took us from comfortably being in the automatic promotion positions to nearly not making the play-offs.
No blinkers on me, mate. No bandwagon been jumped on either. He's an excellent manager, it doesn't take blinkers to see that.
Firstly, I've been accused today of being stuck in the past, but all of Sven's success was in the 1980s and 1990s (when we still had wing backs, by the way). O'Neill's last league title came six years after Sven's last title.
Secondly, you miss the point that Martin O'Neill actually won us promotion in that mediocre season you're talking about, with five wins and a draw in our last five games. And, crucially, he was the guy who pointed out that our very nice passing football had become just a little too predictable for the Championship. Something Sven will have to learn if we're to go up.
Finally, as for 'he's an excellent manager', as I've said, you've got to wait and see. He's BEEN an excellent manager, whether he can pull it off this time we don't know. And if he is an excellent manager, then right now he'll be wondering whether he should have selected Bruma instead of Abe, or Dyer instead of Waghorn too. Until he develops that much vaunted 'Plan B' we won't trouble the promotion race.
Of course, that's not to say that he won't. After all, he has BEEN an excellent manager. In the meantime, we lost a game, and the reasonable thing to do is to wonder why.
