I'm not for one minute suggesting my opinion is correct or any more valid than the net mans but I'm sure many would agree England during the finals have been:
-comfortable in ths system and have a great team bond and spirit
-Played some lovely football at times but not to the extent of creating endless clear cut chances
-Generally took our chances when they've come (Panama the obvious example)
-Been excellent at set pieces
-Coped well defensively but still yet to come under any sustained pressure in a single game.
We've almost certainly had bigger challenges in qualification.
But footballs about winning games and we've got into that habit of doing so when it's mattered and two more of them and we're World Champions.
