Probably not, no.
But to signal that out as a motivational triumph is wrong, IMO. We know it was a tactical masterpiece against all the odds. Other than HT in Istanbul, we don't know what was said and done in the dressing room. And Rafa's since had better squads, full of players he's signed, and got very little from them, so what does that signal? We can't keep going back to 2005, it's too long ago now.
Put it this way, the Chelsea players constantly sang his praises, were madly loyal to the guy, and gutted when he left to the point many considered leaving. It's not based on much, but I'm not sure the same would be true if Rafa left.
