Italy striker Christian Vieri marched out of a news conference on Sunday vowing not to speak to the Italian press again, as tension mounted in the Azzurri camp ahead of their decisive final match against Bulgaria.At least two Italian newspapers reported on Sunday that Vieri, criticised for his disappointing displays, had argued with goalkeeper Gianluigi Buffon after Friday’s 1-1 draw with Sweden. “This is the latest invention that you have invented,” Vieri told reporters after a spokesman for the Italian Football Federation had scolded the press for the story. Buffon also denied there was any truth in the reports. “This is the last day that I speak to you. You can talk about football matters, I’ve never cared less about what you write anyway,” said Vieri.
