How to make an effective defense in PES2012

This is not about full defend, but defending for attacking.  

Look the formation aside :

1. 4 central defenders usually
2. 1 defensive midfielder (DMF) and 1 central midfielder (CMF)

Point 2 is the most important thing in this formation.  

1 defensive midfielder useful to hold the onslaught of the opponent which allows two central defenders behind him ready to determine his position or to keep the other opponent, to minimize opponent to reach the penalty box.  

While a central midfielder can also be used to simply shadowing the opponent before meeting a defensive midfielder, but its main function is as a distributor of the ball from defender to striker or as a playmaker.  

How it works?
When there are opponents who tried to get into our defense area, attached him as soon as possible (not to steal the ball). When opponent was taped as soon as possible also move the cursor to the nearest player to win the ball or tackle. A good tackles and constantly will impact very effectively block the opponent, but if you can not do a good tackle, then do it once or twice just because of bad tackles will invite the referee to give the card.
