I think his affection for the club and his loving relationship with the fans is genuine and, while that doesn't make us bulletproof, it alleviates the stress of a possible sale to some extent.
He clearly gets a lot of joy and motivation from being loved, and you can tell that the stuff with his Dad has made a big difference. He parades his wee'un (and inevitably the next one to come) as little Geordies on social media, and the ties to Big Joe and his family are obviously a big deal to him. I also believe him when he talks about wanting to put his name in the history of the club.
The threat of losing him is real but I think we have a very good chance of convincing him to stay; that's providing that we recover from our slump, and there remains clear evidence that we're on an upward trajectory, even if the shape of the curve is a bit erratic. If we completely fall to pieces then we're in a far worse position to keep him, but I think we'll finish strongly.
Regardless of form, if PSG come flying in and activate the release clause, then it's probably curtains because the club will engage in a sale, and the player's wishes are less relevant. However, is it even realistic that they'd do that? That release clause is miles away from anything they've ever spent on that position. A glance through Transfermarkt would suggest that it would put him behind only Mbappe and Neymar as their biggest outlays. Plus, they're well stacked in that area, including with Ugarte who joined recently.
If anything comes in, my guess is that it will be in the summer and will be a number lower than what we'd be prepared to accept. In that case, it's up to the player to itch for the move. I don't think he will so we'll say: "release clause or fuck off." And that'll be the end of the matter, Bruno's a Geordie.
