This latest... topic is such a pointless thing.
Was it Rangnick's place to reveal this? Maybe, maybe not. Could have just said "personal reasons" and that's it.
Then again, someone else would have picked up on this and posted about it. Or they would just speculate and write bull articles about a supposed storm brewing between Rangnick and Sancho, like they do know. Sancho just has to get used to this. The price of fame and all. It's unfortunate, but it is what it is.
Besides, a week from now no one but the immediately affected will remember or care about the reason he wasn't in the squad.
A nothing burger.
