Two weeks ago he insisted: "The next coach has to have the experience of being involved in competitions like the Euros and the World Cup. That is so important.
"They have to have been there and seen what is required to perform on the biggest stage. England needs someone who has gone through that, not just someone who has only been involved in league football."
So, going against all that, Shearer has thrown Steve Bruce's name into the hat for the England's manager's job after declaring Roy Hodgson's successor should be an Englishman.
Bruce wasn't even capped by England, never mind being involved in the World Cup.
The Football Association are on the lookout for a new boss to replace Hodgson, who resigned following England's humiliating exit from Euro 2016 at the hands of minnows Iceland.
Sunderland boss Sam Allardyce and German Jurgen Klinsmann, the current United States head coach, are reportedly frontrunners to fill the vacant position at Wembley.
But rather than go foreign, like the FA did when appointing Sven-Goran Eriksson and Fabio Capello, Shearer insists the new man should be English.
"The FA constantly talk about wanting their own identity," former England international Shearer wrote in his column in The Sun.
"They bang on about St George's Park and our need to develop the standard and quality of our coaching.
"They insist former players complete their coaching badges in England rather than elsewhere, do their B, A and Pro Licence and climb their career ladder. So how on earth can they consider appointing a foreign manager?
"The FA produced their handbook, the England DNA, and yet here we are, when push comes to shove and a decision needs to be made, they are thinking of hiring a foreign manager again.
"What message does that send out to every aspiring young English coach, or just any English coach for that matter? It would be a slap in the face.
"It would go exactly against what they are telling everyone we should do and exactly against their own system.
"Why can't we have an English guy to manage England? It's not like we have a long list of amazing foreign candidates who are available. It's not like taking that path has worked before."
Shearer believes former Manchester United defender Bruce, who last season guided Hull back to the Premier League, would be perfect for the job.
"I get that there is not a huge list of suitable English candidates. But there are people out there who should be considered and spoken to," Shearer added.
"Why wouldn't they give it to Steve Bruce? He would be my pick. Bruce has worked in English football all his life.
"He knows the game inside out and is widely respected. He has played at the highest level with Manchester United.
"Bournemouth boss Eddie Howe lacks top-level experience but could do a job. If they go for Eddie Howe, that would be fine as well. I wouldn't have an issue with that.
"He is young, energetic and fresh and he would fit with the FA's so-called blueprint. The players would respect him, he's a contemporary of theirs.
"Alternatively, why not do what Germany did and give (Frank) Lampard, Rio (Ferdinand) or (Steven) Gerrard a go, with an experienced coach next to them? If anyone knows where we have gone wrong in the last few years, those guys do.
"They would know how to motivate the younger generation, understand why they fear failure so much, give them ways to cope with the pressure."
