IMO only winning the World Cup will keep Sven in the England job.
The english media go into every tournament with the opinion that England only have to turn up to win it, where they get this attitude from I'll never know, they haven't won anything in 40 years. England always have great individual players, but they have never had a great team, there is always a scapegoat, Seaman, Waddle, Pearce etc.
The other thing the english media is guilty of is having the belief that anyone who pulls on an England jersey is world class, when was the last time one of them won footballer of the year? Beckham is the classic example, he is the most over-rated player in the world, Real Madrid have won nothing since he joined, and IMO Lampard and Gerrard are better players.
Perhaps if the english media didn't have such a condescending attitude, they wouldn't constantly be left with egg on their face, and more people would be more supportive of England ( with the obvious exception of the Celtic nations! )
There are better managers than Sven, but are any of them English, I would love to see Alardyce as England manager, Mike Bassett anyone?
If Sven win's the World cup his popularity will soar, but he will never be able to set foot in Scotland again!!!
