Ferguson, on the other hand, knows the English game intimately and over the years has enjoyed - if that's the right word - relationships of varying warmth with a succession of England managers.
They all have their Ferguson stories, from Sir Bobby Robson and Graham Taylor to Terry Venables, Glenn Hoddle and Kevin Keegan.
Now it's Sven's turn. Just as it's Ferguson's job to protect the interests of Manchester United, it's Eriksson's duty to safeguard the interests of the national team.
To date, he has made unprecedented sacrifices to avoid confrontation with the big clubs. To ease the players' workload he agreed to mass half-time substitutions in friendlies last season and has now given up at least two friendly dates this season.
Furthermore, this week he's released the two Arsenal doctors, John Crane and Tim Sonnex, who had treated the England players for years and replaced them with a Swede, Leif Svard.
There's no suggestion that this has been forced on him, but the introduction of an independent medical expert at the Football Association looks to me like a further sop to Ferguson, especially, and the other Premiership managers.
It cannot be without coincidence, although you won't get anyone to admit it, that the two doctors came from United's main rivals for domestic dominance. Victories like this are important to Fergie, and he has surely won this time.
What does Sven get in return? He turned up at Old Trafford on Tuesday to watch Paul Scholes play for United, 24 hours after he had been told that the player was unfit for international duty.
There's nothing new about this tug of war between club and country, but it's rarely been as important for the England coach to have a good working relationship with the club managers. He has few players to choose from and some of the best are at Old Trafford.
But the England coach cannot allow himself to be bullied by managers.
He must fight his corner and stand up to Ferguson. Surrender is not an option.
That would be the beginning of the end for the amiable Swede.
