Well its what every good team does when you know vividly that the attacking line of the opposite team is way stronger than yours. What you do in a situation like this is always wait and pounce on a counter attack of which was very effective at their own end as they capitalize at every chance they get and scored thrice which was very good from them.
Brian Priske's schemes and plans really worked very well in this match and indeed this is the most brilliant and risky plan for a match when facing a club that is stronger. When the plan with a defensive scheme and a quick counterattack succeeds then indeed the conditions will be very beneficial for the club itself but when the plan has many gaps and our defense is not very effective then indeed it can bring destruction. But what happened for the Feyenoord match was very successful even indeed a great success with a defensive scheme and waiting for the right momentum to make a quick counterattack.
Feyenoord clearly realized that it was one of the most effective ways because if in the end they tried to do other schemes such as trying to keep up with the performance and games played by Bayern then their situation would be a little detrimental so that this scheme was finally chosen and indeed the results were as expected even Bayern could not move even though they controlled the game and even they played half the field.
