It's interesting.
SUFC declared a culture change when we appointed Robson and Jukanovic.
Both tried the shot passing, keep possession game, but the attacks were too slow, so the opposition always had plenty of time to re-orgnanise.
Although the football was decent, the entertainment was below par (especially with Robbo) and results were really poor.
Blackwell and Hecky come in and basically revert to the previous more direct, quicker style and it's instantly more effective.
Swansea had fully adopted this passing, keep possession style for years, it was part of their culture but didn't do them any good.
So adopting a nice, more Premier League style of play, playing "proper quality football", can be overrated and ineffective at Championship level.
