It's a fascinating style of management. Force the team to play in a style that is 10 years out of date, with absurd restrictions on what they are allowed to do on the pitch. Then if they manage to get in front, take off the best players and completely disrupt the rhythm to ensure they lose, as I guess they are supposed to.
Watching Swansea makes me think of teams that still played the traditional 2-3-2-3 in the early 70s, blissfully unaware that the world had moved on.
It must be possible (fairly easy?) to do better than this. In fact, I'm sure it is. The players are much better than this, the players are not the problem.
