"If the results don't come, it is right to criticise and draw conclusions. But only if they don't come," the former AC Milan and Italy midfielder said ahead of Wednesday's clash in Bari.
Under- fire coach says pre- Scotland gloom is premature
"I don't understand why we are already on trial before anything has happened".
Last weekend's Euro 2008 qualifiers upped the pressure on Donadoni, as Scotland and France strengthened their lead of Group B with wins over Georgia and Lithuania, while Ukraine moved passed the Azzurri by beating the Faroe Islands.
So Wednesday is very much a must-win game.
Donadoni stressed, however, that there is no reason for an Italy side that have won their last two Euro 2008 qualifiers to be pessimistic.
"Scotland won on Saturday, but it seemed as if Italy had lost," the 43-year-old said.
"If anyone did not realize, I'd like to remind them that we didn't take the field". Donadoni made a shaky start as the replacement for World Cup-winning coach Marcello Lippi. Italy drew 1-1 at home to Lithuania and lost 3-1 to France in their opening Euro 2008 games in September. But his side recovered in October with 2-0 and 1-3 wins over Ukraine and Georgia respectively.
The sports press have criticized the former Livorno boss for the high number of different players he has called up to the Azzurri squad since taking over - 53.
Some pundits have suggested Donadoni lacks leadership skills, which is why he had been unable to instil a distinctive identity into his national team so far.
They have also pointed out that he has never coached a top club, unlike his immediate predecessors Lippi, Giovanni Trapattoni and Dino Zoff.
Juventus goalkeeper Gianluigi Buffon betrayed some nostalgia for Lippi, whom he described as the best coach imaginable in an interview given at the Azzurri camp.
The Italian sports media have been tipping AC Milan boss Carlo Ancelotti as a possible replacement.
Ancelotti fuelled this speculation last week when he told La Gazzetta dello Sport he would like to train the Azzurri, although he stressed that this would be only after Donadoni's term in charge is over.
The Azzurri players rushed to Donadoni's defence Monday.
"Donadoni is fine where he is," said Italy captain and Real Madrid defender Fabio Cannavaro.
"It is normal for Buffon to say that Lippi is number one, when you have won a World Cup together.
"And it is not true that Donadoni lacks personality. The truth is that you have to be a saint to coach this national team".
AC Milan midfielder Gennaro Gattuso played down the reports that Ancelotti wants Donadoni's job.
"Ancelotti has a contract with Milan that runs until 2008 and he does not want to kick Donadoni out. Besides anything else, he was his teammate at Milan and he has great respect for him.
"Donadoni knows his business. He makes us work a lot and he knows how to organize us on the field of play".
