Losing possession when playing out from the back doesn't necessarily result in goals. If you have the right type of players who can perform well in this system, it will usually results in more points gained than are lost. Regarding goalkeepers, Manual Neuer is great when he plays as an extra defender to beat the opposition press.

This system is pointless for teams like Cardiff though, who simply don't have the players. It may be different for Wales in a few years time, as Mepham, Rodon and Ampadu are all comfortable playing it on the deck and keeping possession.
