Fair comment.
When I saw it, I looked it up (a while back, something out of character for me). His grandfather was a big part of his life. So, still keeping the name was understandable. However, like you said, he could change it but it is what it is.
I’m usually nonplussed by off-field things. Why I detest Bruno Fernandes as he’s a **** on the pitch. Fuck knows if he’s a saint off it. Nonetheless, I can understand why you’re not a fan of Depay. Not to say that I am but the headband, the names, etc doesn’t bother me as much as he’s decent player. There are worse players with more arrogance than him.
