Personally, I believe that the best form of defense is attack, This is because playing an attacking formation pressurizes your opponent, remember, the aim of each football match is to score and attain to a win. When you pressurize with an attack, the opponents looses balance and you will be in possession of the ball while they will be focused at defending.

Waiting for the opponents to attack and then you defend is not a right option because they may end up scoring you even and that keeps the opponent on the safe side while, your team will now be fighting to equalize.

Also, waiting for the opportunity to come before you attack is risky because that opportunity might not come and even if it comes, football is a very unpredictable game, You are not sure that your attackers will score with any opportunity because the opponents are not lame, they'll surely fight to prevent you from scoring.

This is the reason, Manchester City is on top of the premier league table, They are known to be an attacking team, even when they are winning, they never relent while Chelsea on the other hand have lost many of their recent matches because they keep on passing the ball around their own half of the field while they wait for they opponents to come out before they attack. This formation have not proven to be productive to the Blues because those opportunities no longer appear as expected and they end up loosing the match.

Also, playing an attacking games makes your own defense to be at rest and that gives them enough time and opportunity to be more calculative and prepared to know how they will stop any attacker and return the ball to their own attacking teammates.

The success of any football match is victory and a defensive team does not attain to victory and that is why, Jose Mourinho had only one trophy the last time, he managed the Manchester United team for 2 seasons.

Attack on the other hand is one of the attributes of a beautiful football game and team.
