We are suffering from nearly 10 years of Ed Woodward, a man who didn't have the basic foresight to realise off field success is related to performance and discipline on it.
and that's where all this stems from, because now we have players we've signed or even from our own academy with the same attitude, because its the attitude the club literally spent nearly a decade promoting. ETH is probably the first manager post Ferguson who actually has any real license to discipline players or ship them off based on football/attitude grounds rather than how much they make the club in marketing.
Although also I think this is giving Rashford an easy ride. He's championed himself as humble and a hero of the working class children of the country, then flies off to party before training because he's apparently too good for all his team mates, manager, etc. Then turns up to face the music in his solid gold Lamborghini. He's a twat entirely of his own making.
If this happens in Ferguson's day, it wouldn't even just be Ferguson who you'd have a big problem with, the rest of the players would eat you alive if you came in with anything other than an apology and your tail tucked firmly between your legs, and even then any standing of respect you commanded or had built up from any of them would be back down to absolute zero.
