Yes, they are painful to watch and IMO is the worst team of the last 16.It is not just about the shots on goal. The build up play is painfully slow and laborious. I am not saying they are ultra defensive but definitely been the most boring team to watch this World Cup considering other teams play a fast counter attack.
It's just that people keeps thinking that this Greece is ultra defensive, and I don't agree with that. They are definitely a lot more adventurous compared to their 2004 counterparts, although that doesn't mean they are any better. Their gameplan is no longer trying to stifle their opponents.
