I just can't understand this view point. Let the youngsters celebrate it, they may not be old enough to remember the PL won or previous Championship wins. Just because we've been so fortunate over the last few decades doesn't mean the next generation of fans will be.
Same goes for the players - Fatawu, Mavididi, Mads etc. who were all relative nobodies when they signed - they deserve to be celebrated and recognised for their achievements.
You never know what might happen in football, it could be the last major trophy the club wins in your lifetime and you're actively not wanting to celebrate because you expected it? Very odd.
