He shone brighter than his teammates, but not as bright as our brightest ever stars.
I can understand people forming an attachment to him over the last decade, because who else are our young fans going to idolise? But that doesn't mean that DDG is legend material.
To be a legend, not only do you have to be synonymous with the club, the club also has to be synonymous with you. So when I think of Manchester United, I immediately think of Best, Charlton, Beckham, Giggs, Scholes, Cantona etc.
De Gea doesn't get in that list. He's probably a couple of notches below, and there's no shame in that.
