“If it was as straightforward as one thing, it would be brilliant. There are different aspects," said Borthwick.
"The conditioning, to get conditioned to how we want to play, because it is different to how it’s been done previously.
"It’s different to players from different clubs. So I think there is a condition aspect, that is going to come with time. You can’t fix that quickly, all you can do is keep training at the intensity required, ready for the Test matches.
“I think there were some things tactically as well that we needed to adjust in both games so we have looked at those closely, to make sure we are tactically smarter and also conditioned better.”

He added: "I don't separate the physical from the mental, because the two are intrinsically linked. What we have to do is rebuild this team.
"What I've seen this team do, in the Scotland game, is actually come through that period and actually went up on the scoreboard.
"What we didn’t then do is finish the game. And I was pretty frank after the Italy game, I was pretty disappointed with the last 20 minutes of it – how we gave them some opportunities. I was pretty frank about saying our speed of ball wasn’t where I wanted it to be.
"So what have I done? Concentrated on making improvements in those areas. And we know this is an incredible challenge, because [Wales] have got Test caps galore. We are going to have to be very, very good. Can we be the best we can be?"
“Didn’t even call” – Five players who won’t play for England again under Steve Borthwick
Steve Borthwick has been brutal In his short time in charge of England, dropping a number of major stars ahead of the 2023 Six Nations.
Below, we look at three established stars who are unlikely to win another cap.
#1. Joe Marler
Age: 32
Position: Loosehead-prop
Caps: 83

Marler is unlikely to return to the England team during the 2023 Six Nations after he breached one of Steve Borthwick’s main rules.
The new England boss has a “no sh**talking policy” with England, whereby he expects players to behave appropriately on the pitch.
As a result, Marler was left out of the Six Nations squad despite his fine form with Harlequins this season.
Marler’s latest ban was for six weeks – four of them suspended – after accepting a charge regarding comments made to Bristol flanker Jake Heenan about his mother.
At this stage, an international return looks very unlikely.
DID YOU KNOW? Marler started his career at Haywards Heath RFC in Sussex where he played in the same side as fellow England international Billy Twelvetrees
#2. Billy Vunipola

Age: 30
Position: Number 8
Caps: 64
Borthwick excluded Powerhouse No8 Vunipola from the Six Nations squad, opting for Alex Dombrandt from Harlequins and Sam Simmons from Exeter as specialists.
Vunipola made a return to the England squad last summer under Eddie Jones and played in the autumn Test series.
However, in Borthwick's first selection, he made significant changes, resulting in Vunipola being among several experienced players left out.
With Zach Mercer set to return to England this summer, yet another recall for Billy is starting to look very unlikely.
DID YOU KNOW? He is the nephew of two other former international players, Manu and 'Elisi Vunipola, who both represented Tonga in the 1990s
#3. Danny Care
Age: 36
Position: Scrum-half
Caps: 87
Returning to the England squad in the summer for the tour of Australia, Borthwick reported told Care that he had 'no chance' of a recall as he looks to take the team in a different direction.

#4.Jack Nowell
Age: 29
Position: Winger
Caps: 51
With a move to France pending, the Exeter Chiefs flier went from vice-captain in the Autumn to being completely out of the squad for the Six Nations, reportedly without a phone call.

#5. Jonny May
Age: 32
Position: Winger
Caps: 72
The Gloucester speedster, who is England's second top try-scorer of all-time with 35, was another veteran who was unceremoniously axed by Borthwick. h
With injury problems becoming more and more frequent, May will need a significant upturn in form to have any chance of a recall.
Ollie Hassell-Collins is primed to start for England this weekend with the likes of Max Malins, Adam Radwan, Cadan Murley and Henry Arundell all vying for a place in the England team.
