This playing style is based on what successful powerhouses do.

It is harder to play - well. To play it well it is critical players maintain ball possession - and move effectively off the ball in possession. In some  instances this means 'checking' (shaking one's marker by  feinting one way, then running in  the opposite direction with some gained space).

Teams who play like Thailand and Vietnam do against us tend to have limited success at international level over a sustained period.
Van Gaal's AZ Alkmaar and Ajax tried to play the same way.

The same with recent Barca teams that  have adopted the Dutch school of football under the Cruyff influence. That is playing a high line, with the keeper used as a sweeper. The aim is to dominate possession.

Their recent school of thought in Holland is that in the past their players were better technically than their opposition. Recently there is a school of thought the Dutch have focused too much on whole team play as opposed to individual skill development.

Conversely, the Germans who borrowed heavily on the Dutch methodology in the early 2000s in revamping their curriculum, allocate half a player's time on the training track to working with the ball individually.
