I dont know why anyone is surprised
In the last 20 years Portugal have been an absolute disgrace at World Cups and Euros
Despite having some World Class players their whole approach has always been not to lose the game rather than win
And when its clear that the opposition is getting the better of them they pull out the Mourinho rule book of timewasting and persistant fouling etc
Portugal v Holland in 2006 is a classic example
Portugal werent confident they were going to win by skill alone so they tried their best to reduce it to a kicking match and succeeded
