Attack wins matches,defense wins championships!

[Abhinavsharma]

Yes, but it will fail in the sense that you will likely concede a of goals due to the fact that you deliberately allowed the opponent to come in number into your half and yet you ordered your players to stay up the field. In other words, this combination is not compatible.

So a simple conclusion that defense must be capable of snatching ball if opponent come to your half or it will be futile to use counter attacks.
