As JJ said, firstly I don't think City will win it. I make Utd favourites. Secondly, I don't prefer City winning it to Chelsea, so Chelsea winning it doesn't do me any harm.
If it doesn't do me any harm for Chelsea to win it, and coincidentally brings me huge satisfaction from Rafa winning it, then obviously I will be cheering for that to happen, as the net result is an increase in my satisfaction.
