'Happy smiling faces in the morning - in a losing environment - rather than sulkers that win'.
That's how it was put to me by those close to, and in the know, at Manchester City this week.
Mancini lost his job remember because City's highly paid stars didn't want to live 'on the edge'.
Didn't want to work in an environment that 'demanded' of them. That meant they had to 'hurt' to win.
They wanted to be happy. Rely on natural talent. And believed winning was 'easy'.
The owners' phone never stopped ringing - calls from unhappy millionaires wearing City blue that wanted Mancini out.
Now City might yet recover to win the title, but I doubt it. It's been a devastating week.
When they needed mental strength most they were found wanting again. Winning isn't 'easy'.
As many of you know, I'm not Fergie's biggest fan, I don't think he's a nice man, but he created an atmosphere at United second to none when it came to winning.
Ironically, and I know I'm arguing against myself here to a degree, he shares many of the same 'qualities' as Mancini in that respect.
Winners very often aren't nice guys.
I said back in August i believed it was a mistake for City to fire Mancini. In doing so THEY lost the dressing room. Not Mancini.
Never again could a Manager there make decisions that weren't going to be undermined.
With Fergie going it was the time for stability at City. Bury United. An era of unprecedented success beckoned at the club
Not now. Too late. A League Cup win and the last 16 in the C Lge.
And by the way - a scandalous oversight at the group stage when no one at City knew another goal in Munich would see them top the group.
Mancini did - he told me. My top four before a ball was kicked and crucially the transfer window shut, was 1 Chelsea. 2 Arsenal. 3 City. 4 United.
Liverpool could yet make me look a mug - and if they do I'll be delighted! But I wasn't far out. I never fancied City and yet they should've walked it.
As I often say 'be careful what you wish for...' Happy smiling 'losers' - and another change on the cards I hear. Frank de Boer's name is being mentioned now.
Briefly - well done Tony Pulis. I got battered by Palace fans when I backed that appointment. Haven't heard too much from them these past few weeks!
