In that first sentence you have hit the nail on the head, winning and losing.
If you are winning then this is where the entitlement comes in, if you are losing then you have a right to complain about the style of play.
At the end of the day, for me, winning and losing comes first and the style of football comes second. That is the beauty of football, there is more than one way to win a game of football.
Neutral football, is a different argument. Wanting to watch good football when a neutral is certainly not entitlement. However, as I mentioned, I like competitive football. If I went to see a game and it was close and competitive then there is a good chance I would be entertained, regardless of the style of football. If it was 2 teams playing it around nicely but cancelling each other out and not creating chances then that would be boring, if it was 2 teams who play it long more but both created lots of chances, then there is a very good chance that I will be entertained.
