"Time on the paddock is the thing that helps you learn the most, but he will adapt. The biggest things he will have to get his head around are the dos and don'ts in the contact area - the decision-making. But I'm sure he will take everyone to a new level through his skill and his competitive nature."
Yesterday, it was the turn of Farrell's closest colleague, England head coach Stuart Lancaster, to wax lyrical. "Does he have enough time? I guess we'll see," the Cumbrian said in a television interview with Sky. "It's probably a good thing he can have the break he needs and learn the game in a quieter environment rather than be thrown straight into the spotlight.
"He's an incredible rugby player, a great leader, and having spoken to him his mindset is to make the World Cup squad. We have some very good centres who will have something to say about that, but he's an impressive person. You have to admire someone with his mental strength and toughness."
Lancaster is no doubt right on a number of counts. That Burgess was bold and ambitious enough to take up the cudgels in Australia as an 20-year-old says something significant about his character - the NRL is not obviously the place for an English youngster to go in search of tea and sympathy - and in the five years since he has developed an even harder competitive edge.
He is also as tough as old boots. If he can play 79 minutes of a full-on final with his face in need of reconstruction, he might even have withstood the kind of dockyard brawler's assault we saw from Wigan forward Ben Flower in the Super League showpiece against St Helens three days ago.
Yet the coach is equally correct in saying that while England's new Greenwood remains more elusive than the Scarlet Pimpernel himself, there are a number of contenders: those whose claim on the No 12 jersey is immeasurably greater than anything Burgess can offer by way of a job application. Lest we forget, we are talking here about a man who has spent precisely no time whatsoever on a union pitch.
Billy Twelvetrees, of Gloucester; Luther Burrell, of Northampton; Manu Tuilagi, of Leicester; and Brad Barritt, of Saracens, are all chasing starting places at centre in the forthcoming autumn international series against the cream of the southern hemisphere - and, by extension, in the 2015 Six Nations, followed by the main event itself. So are Henry Slade, of Exeter, and Bath's Kyle Eastmond and Jonathan Joseph.
Those last two are currently playing the house down as a midfield partnership, and as Burgess will be playing for the West Country club once his busted bones knit sufficiently for him to fly around the world and touch down on these shores, his immediate problem is obvious. Is it really possible he can elbow aside Eastmond, a fellow cross-coder, in double-quick time? Are the Bath coaches serious about weakening their side for important Premiership and European fixtures, simply to give Lancaster a look at their protégé experiencing match conditions?
And another thing, as they say in all the best arguments - will Bath play Burgess as a centre anyway? Bruce Craig, the outspoken and highly opinionated Bath owner and executive chairman (some would add the title "acting director of rugby" to that list), has indicated more than once that the new signing might find a home in the back row rather than in midfield.
What is more, the former England coach Brian Ashton has been heard to suggest that when push comes to shove, Burgess will be a blind-side flanker rather than an inside centre - and Ashton knows as much about the union-league nexus and all it entails as anyone in Europe.
If, as the Rugby Football Union has indicated, Bath are the sole financiers of Burgess's navigation of the great gulf between codes, Craig and company have every right to do what they like with him - and just at the moment, the Recreation Grounders are in far greater need of loose forwards than backs.
Which begs yet another question: namely, the precise terms of the arrangement under which Burgess is heading for these parts. More than one Premiership club has yet to be convinced that there is no RFU money in the mix, and there will soon be calls for complete transparency over the matter.
One way or another, then, the idea of bringing a brilliant rugby league player back to England and turning him into a brilliant union player for the benefit of the nation is fraught with problems. At the very least, Lancaster runs the risk of fracturing the unity of his squad by fast-tracking an individual at the expense of players who already have "credit in the bank", to borrow one of the coach's favourite phrases. It is a sensitive issue, in need of careful handling.
Midfield minefield... six cross-coders who took on the centre challenge
Kyle Eastmond (Bath)
The smart-stepping Mancunian was a mixed bag in New Zealand in June, but his progress this season has been startling.
Cross-code success: 7.5/10
Andy Farrell (Saracens)
A rare talent whose union career was wrecked by injury. Patently a "Test Match Animal", but never at his best in 15s.
Cross-code success: 6.5/10
Joel Tomkins (Saracens)
A little fortunate to win union caps a year ago, he returned to league admitting that 13s suited him better.
Cross-code success: 5.5/10
Henry Paul (Gloucester)
A sublime footballer with serious game management issues. Won six full caps but was never fully accepted, for all his skills.
Cross-code success: 5/10
Barrie-Jon Mather (Sale)
A big-money trailblazer whose union career was on the rocks after one England appearance. Never lived up to the hype.
Cross-code success: 4/10
Chev Walker (Bath)
A big-news signing who failed to adapt to union and was back in league in the twinkling of an eye.
Cross-code success: 1/10
