England assistant manager Ray Lewington has revealed that manager Roy Hodgson is not always as calm behind the scenes as he appears on the surface.
Lewington, who also worked under Hodgson at Fulham, said that his boss wastes no time losing his temper with the players should he feel that they are underperforming.
"What you see is what you get with Roy, but people will be surprised to hear that he has a nasty side to him too," Lewington told Crystal Palace's official website.
"You ask some of the members of the Fulham squad. They know about it. It wasn't a forced anger. When he was angry he was genuinely angry and the players knew about it."
England are in a World Cup group with Costa Rica, Italy and Uruguay this summer.
