I like that Xhaka isn't going to apologise. Let's call a spade a spade - he doesnt 'love the club', he doesnt 'love the fans', it's a job and Arsenal just so happen to be his current employer, an employer that he will probably be parting ways with in January. Likewise, the fans have nothing but disdain and bile for Granit Xhaka so let's just call it what it is - no love lost and a player who won't be wearing the armband again nor the shirt again, most likely.
Shake his hand, sell him in January while Arsenal can still make something off of him, move him on. No need for pleasantries from Granit - the fans won't be returning the favour either. Move on.
Is it what you'd expect of a captain? Of course not, hence the armband is moving elsewhere now.
It's also not what any footballer should expect of his fanbase, or at least a fanbase he wants to continue to be associated with. I would never want to play for Arsenal again if the fans had been calling me a cnut and insulting / wishing harm on my pregnant wife or whatever it was. Feck them.
Again, move on. Done and dusted. Breakups happen all the time in football.
