Daniele De Rossi sent a video message to the Italy fans watching tonight’s World Cup qualifier against Spain.
It kicks off at the Bernabeu in Madrid at 19.45 UK time (18.45 GMT).
“This is the big night, we are playing this very important match at the Bernabeu,” said De Rossi in his Instagram recording.
“I wanted to thank all the fans who will be at the stadium, I know there are over 2,000, and also all those who are watching from home.
“I ask everyone to give us great support and we hope to give you great joy in return.”
Italy have not beaten Spain on their own turf in 68 years.
Only the group winners go directly into the 2018 World Cup, with the runners-up requiring a play-off round.
The two sides are currently joint top of the group, with Spain ahead on goal difference.
