Billy Vunipola has allegedly made some interesting comments in the presence of some media after some beers that Farrell pretty much lead the squad, and Burgess got picked due to Farrells coaching to play like rugby league.
I've not seen a reliable source although these comments make sense to what I have seen in this World Cup.
There is a transcript of Vunipola's comments in a discussion with Kyran Bracken doing the rounds on a couple of rugby forums.
From the Leinster Forum:-
This showed up on one of those rugby banter pages and was apparently found on the Quins forum:
"From a friend before the game yesterday:
So, it turns out Kieran Bracken’s next-door neighbour is the senior partner at a City litigation law firm called Stewarts Law. Last night they held a RWC gathering which was hosted by Bracken. As part of the proceedings—after David “rent-a-gob” Campese had spent 15 minutes railing against everything in modern rugby—Bracken got hold of the mic and did a Q&A with injured England no. 8 Billy Vunipola! who had a beer in his hand and appeared to have a couple more inside him…
Bracken:
When you were interviewed after the game against Fiji you said you didn’t know you’d scored the bonus-point try—that was a strange thing to say…
Billy:
Not at all. None of us knew bonus points were part of this world cup. No one had told us.

Bracken:
What’s Stuart Lancaster like to work with as a coach?
BillyV:
I don’t know.
Bracken:
What do you mean?
BillyV:
Stuart doesn’t coach the team, Andy Farrell does. I’ve never been coached by Stuart.
Campo, butting in:
What effect has that had on the way the team plays?
Billy:
He makes us play like a rugby league team.
(Campo then goes off on one about England’s terrible style of play is and how the RFU should just bite the bullet and hire an experienced international coach. To be fair, he’s absolutely spot on with that).
[…]
Campo:
So what do you think about England picking Sam Burgess?
BillyV:
It’s been disruptive. The whole squad is unhappy about it.
Bracken:
WHAT? Why?
BillyV:
Luther Burrell earned his place in the RWC squad and Sam didn’t. Luther should have been picked, not Sam.
[…]
Bracken:
And how are you enjoying playing under Chris Robshaw?
BillyV:
*Shrugs shoulders, sips beer, says nothing*
So, that’s OK then.
Meanwhile Jake—who seems to have got himself quite close to the England camp—is saying that Mike Catt walked out of last week’s selection meeting and vowed not to return: seems Farrell is not only coaching the team but picking it as well…"
