Can't help but find this thread a bit embarrassing.
Like Pellegrini or loathe him, he won us only our second league title in 40+ years, two domestic cups, and this year took us further into the Champions League than we had any right to expect. And I know it's become a cliche, but he's also led us with considerable dignity, despite the constanting sniping in the press.
Has he underperformed over the past 18 months or so? Course he has, badly. Has this league campaign been a disaster since the Autumn? Definitely. Has he made decisions that warrant criticism? Absolutely. Do the fans have the right to vent? Sure.
But I really wouldn't have thought it so difficult to give him a polite send-off, out of respect for his efforts at least. All seems a bit sulking teenager to me.
