England coach Sven-Goran Eriksson has mounted a staunch defence of his tactics following England's lacklustre progress to the World Cup quarter-finals.
The Swede has become more defiant as he nears the end of his time in charge of the national team and reacted badly to suggestions that he doesn't know what his first-choice formation is.
He fumed: "If we have only one system, you will ask me where is Plan B?
"We can use one or two systems - we have two at least - and don't tell me I don't know what to do. I know exactly what to do.
"If we have two systems you will ask me where is Plan C? What do you want me to answer?
"You have always doubted me, so there is nothing new about that. I have a clear vision, we all have, together with the coaches.
"Do you think we just tell the players to go out and say 'good luck, do whatever you want to do'?
"If it is right or wrong is another thing, but it is clear what we do every minute we are together. I know exactly what to do."
