Considering we wouldn't have won the league without him, yes, we *do* need him
And the reason you hate us is because Cristiano Ronaldo forced you to sell to us, and De Gea did the same two years ago
Is that genuinely what you believe?
No you have ruined lots of young players by signing them and then discarding them like there old toys.
Your all time number 1 goalkeeper who served your club for his entire career wasnt given any kind of send off or thank you he was snuck out the back door.
Di Maria didnt want to leave he'd just had one of his best ever seasons helping you win a CL final and you binned him off.
Morata had a great season at Juventus he enjoyed himself, wanted to stay and actually have a career in football but like spoilt brats Madrid forced him to go back and sit on a bench.
Ronaldo has absolutely nothing to do with it he loves this club and fergie more than he ever will Madrid and its self entitled supporters, you were nothing more than a mans dying wish granted.
I could go on in depth about how many talented youth players you've completely ruined too but I'd be here far longer than i want to be.
Lets just say the hatred runs much deeper than you think and his nothing do with Ronaldo or De Gea.
