Foster said the 27-year-old knew how close he was to All Blacks honours when he headed to the northern hemisphere.
"It's a great occasion playing them at Twickenham and hopefully I will get the opportunity to be part of it".
"It's like everything - when you're selecting a national team, there's a whole lot of good players that don't quite make it". As he said, the experience will be invaluable for all the players involved, plus the coaches who will now know far more about them, so while it may have carried risks it was a gamble that has clearly paid off.
"Tom injured his ankle and we don't how long he'll be out for, but he won't be back for our next three Tests", Borthwick said.
"We've moved on a lot so apart from personal achievement I think it's hard for the group to take anything from it". "And he's just a loosey (loose-forward) who plays for England".
His decision to change tack and chase honours with England has previously polarised opinion in the game, but Foster remained personally phlegmatic about the issue.
Arsenal boss Emery upset for Welbeck after 'big injury'
Keown said : "He is the closest thing to Thierry Henry that I have seen since he left the club, he really is that good". And while Nelson may not be a ready-made replacement for Welbeck, Emery says he is keeping a keen eye on his progress.
"The only people that don't understand what it's like to be a head coach of an global team are the people who have never been one", Hansen said.
"So I think it's important when you now talk about Saturday it's a totally different mindset because it's about today". It is what it is; he's not alone, there's a few more in a few other teams.
Not even questions about Barrett's inconsistent goal kicking in losses to the Springboks and Lions in Wellington over the past year could unsettle Foster. "We usually talk either by text or by phone, probably every second week", said Hansen.
"To be honest if you asked me two weeks ago, I was having six months off, so to be sat here now is unbelievable".
"Where these England and Ireland games are pretty special for us is they're one-off games".
"There is a lot of pressure there all the time".
