Barcelona beat Valladolid 1-0 but were left fuming by a dangerous playing surface that endangered players on both sides.
Valladolid relaid their pitch just four days before the game and it showed.
‘We had to work hard because of the state of the pitch,’ said Gerard Pique. ‘They want to play a game in the United States by this is an embarrassment. I hope those responsible do something about it because it was lamentable.’
