Sven should be leaving, not after the World Cup, but with immediate effect. I think that the situation will have an even more negative effect on the players and of course Sven himself. Sven was never passionate about the team and he was just too busy looking after himself.
Good riddance, his behaviour since taking the job has been a disgrace. Whether he's sleeping with FA secretaries, flirting with Premiership chairmen or selling his players out to 'fake Sheikhs', his personal conduct has done nothing to suggest that he's committed to his job or his players.
The timing is absolutely barmy, typical FA. Imagine being told that you are going to be sacked in six months but, in the meantime, go out and win the World Cup. His mind will be on his next job, not on England winning the World Cup, but at least now we we have an excuse for not winning.
