'We didn't adapt': Underhill identifies the area of England's game that must be lifted

England flanker Sam Underhill believes the battle of the breakdown will be pivotal to levelling the series against Australia in Brisbane.

Wallabies openside Michael Hooper was the dominant figure in the hosts’ 30-28 victory in the first Test in Perth, ruling the contest on the ground including winning one game-changing turnover.

Underhill is now poised to replace Tom Curry, who suffered a concussion in the first Test, and the Bath back row insists dominating the breakdown will be key to ending England’s four-match losing run.

“We controlled areas of the game pretty well for a decent chunk of the game but ultimately penalties and discipline cost us,” Underhill said.

“Whether the breakdown was more competitive than we thought it would be or not, we didn’t adapt to the interpretation at the breakdown.

“You can’t have an attack without a functioning attacking breakdown and vice versa – you can’t defend indefinitely, so the breakdown is a pretty good area to target if you want to stifle an attack.

“It is always a massive area of contention, especially in Test rugby against southern hemisphere sides and especially Australia who go pretty hard at it. If you get the breakdown right everything else becomes easier.

“Hooper is obviously a big breakdown threat. It’s not a case of man-marking him but as a team you are acutely aware that if he’s around the breakdown it’s highly likely he’ll be competing. You have to shift him early because he’s good over the ball.”

Curry was ruled out of the tour after suffering a concussion in the first Test, his third head knock in the past six months.

Underhill was sidelined for more than two months after suffering back-to-back concussions either side of Christmas. His empathy for Curry is mixed with concern over the growing size of the collisions.

“At Test level Tom is a machine and I’m gutted for him that his tour is over early,” Underhill said.

“It’s pretty essential to get that recovery right. I have been there earlier in the season with concussion and it’s not something to mess about with.

“Rugby is a more physical game than it has ever been. There are big athletes who move very well and at Test level you don’t have a lot of time to react. The collisions are quicker.”

Despite his concussion struggle, Underhill believes the tackle height laws have made the game safer and more entertaining.

“The laws around tackle height and stuff are having a good effect on the game but ultimately if you tackle lower it is harder to affect the ball speed, but ultimately it creates a more entertaining game. I would argue that would be a good thing on the whole,” Underhill said.

“I would like to see players working with refs and vice versa because at the moment I think maybe it would be better for the game if there was greater understanding.”
