Ben Youngs, centre, celebrates what he thought was a try against the All Blacks on Saturday night.

OPINION: World Rugby boss Brett Gosper can instruct the person tasked with engraving the Webb Ellis Cup to add England's name to rugby's most treasured trophy.

Because it's going to take something extraordinary in Yokohama on Saturday night (NZT) if South Africa are to deny Eddie Jones' gang of bruisers from powering England to a second World Cup triumph.

A day after his side chewed up and spat out the All Blacks to advance to the decider for the first time since 2007, Jones was spotted jotting down notes during the Boks' 19-16 win against Six Nations champions Wales in the second semifinal.

Donning a Houston Texans cap, nothing will have alarmed him, or defence coach John Mitchell, who sat to Jones' right during the tight contest, which was decided by a late Handre Pollard penalty.

Heck, somewhere England's Owen Farrell probably smirked through the entire match as South Africa and Wales failed to trigger any alarm bells.

Lock Maro Itoje, such a force against the All Blacks, might have even hollered and hooted alongside Farrell. That's if the match didn't put him to sleep.

No disrespect to South Africa, but if England can put a blanket on the All Blacks' attack, don't think for a second their white wall is going to have a problem with theirs.

They offered very little on attack in the semifinal, which featured more kicks than a game of football, and was locked at 9-9 until Springboks midfielder Damian de Allende scored the game's first five-pointer in the 56th minute.

Of course, it won't be a walk in the park for England, despite The Daily Mail claiming the Poms "took rugby to a new level" during their 19-7 victory against New Zealand.

AP Wales and South Africa's semifinal in Yokohama was a stop-start affair.

Their attack remains underwhelming, but it simply doesn't matter when they defend like a famished pack of wolves and their set piece is anchored by monsters such as Mako Vunipola and Itoje.

Then there's Jones' genius and Farrell's and George Ford's kicking game. Don't bet against it being a similar scoreline to the 2007 World Cup final, which South Africa won 15-6 against England.

South Africa at least boast a beefy pack of their own, led by outstanding captain Siya Kolisi, Pieter-Steph du Toit and Lood de Jager.

They'll ensure it's a slugfest up front, but it's alarming when the Boks' go-to weapon - outside of a forward crashing the ball up - is a Faf de Klerk or Pollard box-kick.

Wouldn't it be nice if some of their talented backs such as Makazole Mapimpi got a chance to strut their stuff?

Desperate to match the All Blacks for three World Cup titles, South African fans will be quick to point out their side holds a 25-15 head-to-head edge against England, but their counterparts can respond by reminding them England have had the edge recently.

Including 25-10 and 12-11 scalps in Cape Town and London respectively last year, England have won three of the last five tests between the teams.

Let's hope next weekend's final isn't as dour as the 2007 decider.

Just don't count on it. After all, there are no style points awarded in finals.
