Control yourself. That's the warning England's players received from coach Fabio Capello heading into the World Cup, captain Steven Gerrard said Thursday. The need for discipline in Saturday's opening match against the United States was highlighted Monday when striker Wayne Rooney got a yellow card in a training game after swearing at the referee. The Brazilian referee and his assistants who will take charge of the high-profile Group C opener also told Brazilian media they have been studying English-language obscenities the players might hurl at them. "In this day and age I think it's important to show the referees some respect," Gerrard said. "You don't use any language because then you'll be booked and the whole team suffers. You don't want to fall into that trap ... "We've had experience of losing big players at important times." ESPN.com
