Did we play 'good football' in the Sven years? The side was unbalanced for most of it IIRC. 2004 was exciting because of Rooney - I do believe we'd have won that had he not got injured.
Anyway, with the players we have now, it would be good for Southgate to be getting somewhere near the best out of them so we could have some confidence that when we do face a top side, we won't go out pitifully. But he gets absolutely nowhere near the best out of them because he picks an unbalanced side and doesn't drop players who don't work in the system.
