Capello showed his anger on the touchline against Slovenia
England boss Fabio Capello is ready to show his ruthless streak if his players do not tighten up defensively.
The Italian was left irritated after a lapse in concentration allowed Slovenia to score in England's 2-1 friendly win.
If England beat Croatia on Wednesday they will book their place at the 2010 World Cup finals and Capello has issued a thinly-veiled warning to his squad.
"Sometimes I shout. But this time not I will explain what I want them to do - if they want to stay with me," he said.
England have kept a clean sheet in just seven of Capello's 17 games in charge since December 2007 and there are signs he is becoming frustrated.
I have no problem with Glen Johnson

"I was not happy to concede a late goal because the concentration was not good in the last four or five minutes," said Capello after the Slovenia match.
"I want the players to focus and concentrate on every minute of the game.
"During training we tried some movements. But I didn't see them on the pitch. I was not happy about that.
"The mistake for me is when the players don't make the movements I ask."
Two of the summer's big money Premier League transfers came in for criticism after the Slovenia match with Liverpool's £18m right-back Glen Johnson and Manchester City's £22m centre back Joleon Lescott both at fault for Slovenia's goal.
