Burnwinter because, whatever your facts say, Saliba isn't going anywhere. I do get the worry, really I do, but your musings in this thread read like someone's anxiety dream.
Listen to what he is saying, listen to what those around the club with knowledge of the negotiations are saying, look at his demeanour on the pitch and where we are in the table.
Saliba may yet decide to burn all of this to the ground, but, based on the mood music around him, I don't think that's a logical conclusion to this saga. That's why I wouldn't worry.
And also because I try - and boy do I try - not to let things I can't control bother me. I've got enough stress on in my life at present.
