I think the point is the game is finished and there are other opportunities to win a trophy this season. There's no time machine we can't go back to the past and re-play the game so why mull over it?
People don't tend to enjoy having a result in which they lost told to them over and over.
I understand your view. My point was a lot of fans saying they didn't care,didn't take it seriously. That makes no sense we're not exactly trophy laden and with teams like City and PSG spending a fortune it seems foolish to not take a trophy opportunity when one comes along. From my perspective the league cup is the best chance to win a trophy for any club. That includes us.
