it felt like Inter Milan vs Barcelona all over again....

Mourinho secretly give tips to Spain's group opponents?

hmm...defense is also a type of tactics in football match(in fact in every sports)....imo playing good defense is even harder than attacking simply because:

1. you don't know where/how will your opponent attack, its all down to guessing/hunch/instinct...what ever you call it

2. players must have high level of discipline to play defense, one slack/losing concentration will cost the team dearly

3. must be extremely careful since offensive players will have the fouling advantage over defensive players....

still believe the saying: offense will win you games, but defense will win you championships
