On The Rest is Football podcast, a listener asked: "Why has Alan's stance on Isak transfer saga different from when Trent Alexander-Arnold decided to leave Liverpool to join Real Madrid (Especially since he isn't a Geordie, Newcastle will get in excess of £100m for him)?"
Shearer replied by stressing that Alexander-Arnold handled himself differently.
Alexander Isak is pushing for a move away from Newcastle.
In response, however, Newcastle released a statement of their own, stressing that no promise of a future sale had been made and reiterating their stance that Isak will not leave unless Liverpool pay the club's $202 million (£150M) asking price.
I think we're just sat here guessing, but last night's statement hasn't done him any favours whatsoever in terms of trying to get Newcastle onside or forcing them into a decision, I think they'll just go the opposite way."
Shearer has repeatedly expressed his displeasure at the way Isak and his camp have managed the saga, while stressing that his assessment of Alexander-Arnold's departure from Anfield was more sympathetic.
Alexander-Arnold sealed his move to Real Madrid this summer with only one month left on his Liverpool deal.

Although Shearer's words about Isak sometimes mirrored his tone on Alexander-Arnold, he has consistently avoided calling for the Swede to get the same kind of send-off he believes the Liverpool star deserved.
"You have to get the very best deal for the football club and if someone is prepared to pay north of £150m, and if he [Isak] really, really wants to go, you can't step in his way," Shearer said in July.
"Isak has been brilliant for Newcastle, helped us achieve our dream of winning a trophy and if there's no way whatsoever that he can be persuaded to stay at Newcastle, then they have to get the best deal possible and if someone's prepared to pay what they want, you have to say thank you and build for the future
