Paddy Barclay told the Sunday Supplement that Roberto Martinez has all the credentials to manage at the very top of the game.
Martinez guided Wigan to a shock FA Cup final victory over Manchester City on Saturday evening, with Ben Watson nodding home an injury-time winner to land the Latics their first major trophy.
The Spaniard, who took charge of the DW Stadium troop in 2009, has been linked with the managerial hotseat at Everton, which will be vacated in the summer when David Moyes succeeds Sir Alex Ferguson at Old Trafford.
And Barclay says Martinez has the calmness and tactical nous to flourish in the dugout for years to come - whether or not Wigan are relegated from the Premier League at the end of the current season.
"Martinez put in a wonderful tactical performance in the FA Cup final and this man really is a biggie," said the Independent and London Evening Standard scribe.
"It is strange to think that he is only 39 because he is a man of such maturity and should be held up as a model for managers of how to comport themselves, while he is also such a relaxed and nice bloke.
"He really is something special and now he has the indelible mark of an FA Cup win [on his CV] which will be remembered more than and for much longer than Wigan's possible movement between divisions."
Daily Mail writer Ian Ladyman praised Martinez's coaching capabilities, too, as well as the way he reacted to Wigan winger Callum McManaman's agricultural challenge on Newcastle's French defender Massadio Haidara in March.
But he says the FA Cup final triumph is also a "great achievement" for the Latics, who were playing in the fourth tier of English football in the mid-1990s.
"Martinez is clearly ready [to progress up the managerial ranks] because he is a very, very good coach," said Ladyman.
"Plus, the way that he handled the McManaman incident spoke volumes for his style of man management and, as [Wigan chairman] Dave Whelan told me a couple of weeks ago, he wears the job so well."
Ladyman added: "To understand the scale of Wigan's achievement you have to know how small that town is, how difficult it has been for them to attract supporters with the shadows of Liverpool and Manchester United close to them, and how limited their resources are.
"It is astonishing where they have got to and it is one of the greatest achievements to get to Wembley and win the FA Cup playing [a stylish] brand of football and thoroughly deserving to beat Manchester City.
"It is difficult to put into words."
