Can I beat him?

[Tactician]

7:0 haha never possible with hard defending and low press .But wait 3-4☆ stars squad can conceed that much.

It is possible because he forced counter attacks. I told you once on one of your threads that in some cases you can't allow the opponent to come in your half freely and attack if the attackers are too strong for the defence to handle them.

Defending is one thing, hard defending is another, but the combination of any of those two with force counter-attacks is very different. What might have happened here is that the opponent pushed most of his players up and he out-numbered the defending players. This is one of the possible tactics used to beat a defensive with counter-attacks 4-5-1(V).
