I don't have any issue whatsoever with how people feel towards Pellegrini at the moment, mate. Nor with most not being bothered about him leaving. I'm not either, and had the whole Pep situation been otherwise, I'd have been in favour of getting rid at the back of end of last season, when we'd obviously lost our way.
I just think a bit more respect in view of his overall achievements/efforts might be appropriate.
As for the comments about the titles he's won with us - everyone's entitled to their view, of course. Personally, I think any suggestion that he won the title with Mancini's team is utter bollocks (different players, different tactics, and overlooks how poor we were for the entire 2012/13 season). And I'm also far from convinced by the arguments about the league cup v FA Cup - fans certainly see the FA Cup as more prestigious, as does the media. I'm not sure the clubs see it that way, and the timings of games often make it easier to play stronger sides in the League cup (i.e. before the business end of the season).
