Retard it's only normal for them to play bad. The do not want to accumulate unecessery fatigue on the start ofc that the players would most likely want to keep their stamina / strenght when the right time comes and to be more precise when they meet up with someone really good. Groupes are pretty much fucked up take Argenitna's group for example how would you not say they play good when they score vs one of the weakest amongs the Modial 2010 participants ?
Anyway... when groupes are over and those who pass decided then we will enjoy football for now I suggest you go and bet easy money on X matches and wait .
PS: Y-day's match Cameroon/Denmark [imho Denmark should have lost so many mistakes infront of the goalkeeper too bad football].
