The Newcastle striker is attempting to force a move away from the club and escalated the saga with a statement on Instagram on Tuesday (19.08.25) declaring that "the relationship can't continue" - a move that has left Magpies legend Shearer far from impressed.

He told Betfair: "If I was him, I'd get his agent in a room and sack him on the spot immediately, because he is meant to be giving him the advice to sign that six-year deal and there's no get out clause.

"I mean, it's ridiculous. And to take anyone's word in football ... it's nonsensical to say that someone said, 'Oh, I'll be able to get out at the end of the season.' Really? I mean, come on.

"I've always said there are two sides to every story, but my feelings are exactly the same: he's gone about it in the wrong way.

"I just think even releasing this statement has thrown flames onto the fire, which he didn't need to do.

"I get that we needed to hear his side of the story and we've heard that now, and I'm not saying I don't believe him or I don't believe Newcastle, I'm just saying it's very, very messy for him and for the football club. It doesn't benefit anyone."

Isak had accused Newcastle of breaking promises about a move, although the club have denied assuring the Swedish striker that he could leave.

He posted: "The reality is that promises were made and the club has known my position for a long time. To act now as if these issues are only emerging is misleading.

"When promises are broken and trust is lost, the relationship can't continue."
