Sweden right-back Emil Krafth has accused England opponent Ashley Young of going to ground too easily and admits that he cannot afford to give the officials a decision to make.
Young has been labelled as a diver in the past after winning a number of contentious penalties for club side Manchester United.
As a United supporter, Krafth acknowledges that keeping the 32-year-old quiet - if he is selected to start - will be a tough task in Saturday afternoon's World Cup quarter-final showdown.
"I am a Manchester United supporter and I have seen Young a lot - a good player who is very fast," he told reporters. "He likes to cut inside and shoot. In the box, we will have to look for his diving. Not do anything stupid."
Young has played the full 90 minutes in three of England's four World Cup matches thus far.
