Will Greenwood expects England's Rugby Football Union to opt for a "super coach" to replace Stuart Lancaster rather than a home-grown option.
Lancaster's three-and-a-half year tenure came to an end on Wednesday after he stepped down from the top role following a review into England's performance at the World Cup.
Under his leadership England became the first host nation to miss out on the knockout stages of a World Cup, defeats to Wales and Australia condemning them to third place in Pool A.
The 46-year-old's departure by mutual consent triggers the start of the search for his replacement, and Greenwood expects a big name to be appointed.
"I don't think they'll go with a young English coach that hasn't won major trophies," he told Sky Sports News.
"I suspect they will go for one of the 'super coaches', who have won big tournaments such as Super Rugby, European Cups, Rugby Championships, Grand Slams and even World Cups.
"That list looks to be Warren Gatland, Steve Hansen, Wayne Smith, Joe Schmidt and Vern Cotter - these sorts of characters who have a vast pedigree in terms of winning major trophies and experience when coping with unbelievable levels of pressure, which is the way the England job is now.
"It carries with it so much more than just a whistle and a tracksuit, media responsibilities and sponsorship. The job title is the biggest in the world, and that's not said in an arrogant way."
However, Greenwood does expect a home-grown talent to take control further down the line, with Exeter Chiefs' Rob Baxter top of his list.
He added: "Long-term, Rob Baxter would be one to keep an eye on and I hope they are monitoring and mentoring him.
"He has worked wonders with Exeter Chiefs, but the home-grown coach looks to have its days numbered at this stage."
