I think this is a very valid point, and one I wholeheartedly agree with. Look at how Chelski won the Champions League a couple of seasons back. Of course their fans celebrated like mad and were proud as hell, but their win will forever be remembered as the trophy they shouldn't have had, the one they fluked and didn't deserve, the one they bored people out of their minds to get. Similarly, why was our 2008 League Cup win so good? Because we beat City away in the quarter finals, we hammered our main rival, Le ****, 5-1 at home in the semis, and crowned it by beating our other rival, Chelski, in a final in which we were by far the better team.
It's a bit of a silly cliché, but to quote Billy Nick - "It's no use just winning, we've got to win well."
