I don't think it's england fans wanting the passing style. I think large portions of them prefer the more industrial English style. I think it's brighton, arsenal, swansea fans on the whole, with sprinklings from each club wanting the more advanced, spanish/german/etc passing style.
I also think the excuse of not enough time to train them isn't going to go away. National coaches don't have that time that club coaches have. Roy had from the end of the season, he had the full pre-tournament time to dill the players in the passing style we want. That's all he ever would have had. With friendlies and qualifiers so few and far between, players will come to england for a couple of training sessions, a match, then it's back to club level, back to doing exactly what they do with their clubs, forgetting everything they did with england, then it's starting again when they go back for the next international a couple of months later. The most prolonged time an England manager will have with his squad is from the end of the season until they are eliminated from that summer's tournament. Roy had that.
The problem is that the players that need to don't generally play that passing/comfort in possession style at club levels that needs to change. We need more swanseas, more arsenals, more brightons at all levels (and I don't mean to suggest brighton are as good at it as arsenal or swansea, but as an example of a team trying to play it and improve at it).
You are aware that Man City, Chelsea and even Spurs had a better passing accuracy than Arsenal, right? Yet their play is more direct that Arsenal or Swansea. There is a big difference between being able to pass to feet, and playing attractive, attacking, penetrative football.
All too often last season Swansea and Arsenal were just that. They could pass and look pretty, but when it came to cutting edge, they didn't have enough. The same could be said for Brighton in many ways. It's one thing being able to pass between defence and midfield and look pretty, but it's quite another being able to tear teams apart, score goals and WIN games.
I agree with most, we need more onus to be put on technical ability for our younger players. However, I don't think we need to start slowing games down by passing to death. English leagues are renowned for their fast, attacking football. I think this needs to continue into the national team, personally.
