Too many teams are just far too negative these days. Especially in the first round of games 90% of teams would take a draw.
The Ivory coast - Portugal game today is a good example, either side wins and they've almost secured their place in the next round but both teams are just happy to sit and play out a 0-0.
I'm still not convinced it's the balls fault, it's probably playing a part as well as the constant vuvuzela noise and the high altitude. Hopefully the next round of games will bring a few more goals and some more expansive football.
